- Uniform table and figure formatting
-
Avoid False Precision
Good: Mean age = 45.2 years (SD = 12.1) Poor: Mean age = 45.23847 years (SD = 12.08934)
Reporting Guidelines by Study Type
Randomized Controlled Trials (CONSORT)
Essential Reporting Elements
-
Participant Flow
CONSORT Flow Diagram: - Assessed for eligibility (n = X) - Randomized (n = X) - Allocated to intervention (n = X) - Received intervention (n = X) - Analyzed (n = X) -
Baseline Characteristics
Table 1. Baseline Characteristics Characteristic Intervention Control Total (n = 150) (n = 148) (n = 298) Age, years (mean±SD) 62.3±8.1 61.8±8.4 62.1±8.2 Male sex, n (%) 89 (59.3) 85 (57.4) 174 (58.4) -
Primary Outcome Results
"The primary endpoint of [outcome] occurred in X participants (X%) in the intervention group and Y participants (Y%) in the control group (risk difference X%, 95% CI: X% to X%; p = 0.XXX)."
Observational Studies (STROBE)
Key Reporting Requirements
-
Study Design and Setting
"We conducted a retrospective cohort study using data from [database/registry] covering the period from [date] to [date]. The study included [population description] from [number] centers in [geographic area]." -
Exposure and Outcome Definition
"The primary exposure was [definition with coding/measurement details]. The primary outcome was [definition with validation method if applicable]." -
Confounding Control
"We adjusted for the following potential confounders: [list]. Variables were selected based on [clinical knowledge/statistical criteria/literature review]."
Systematic Reviews and Meta-Analyses (PRISMA)
Statistical Reporting Requirements
-
Search and Selection
PRISMA Flow Diagram: - Records identified (n = X) - Records screened (n = X) - Full-text articles assessed (n = X) - Studies included (n = X) -
Heterogeneity Assessment
"Statistical heterogeneity was assessed using the I² statistic. I² values of 25%, 50%, and 75% were considered low, moderate, and high heterogeneity, respectively." -
Meta-Analysis Results
"The pooled [effect measure] was X (95% CI: X to X; p = 0.XXX; I² = X%; [number] studies, [number] participants)."
Statistical Methods Section
Essential Components
Sample Size and Power
-
A Priori Power Analysis
"Sample size was calculated based on detecting a [effect size] difference in [primary outcome] with 80% power and α = 0.05. Assuming a [control group rate/mean], [sample size] participants per group were required. To account for [dropout rate]% attrition, we planned to recruit [total sample size] participants." -
Post-Hoc Power Analysis (Generally Discouraged)
Note: Post-hoc power calculations are generally not recommended as they are directly related to p-values and don't provide additional information.
Statistical Analysis Plan
-
Primary Analysis
"The primary analysis followed the intention-to-treat principle and included all randomized participants. [Primary outcome] was analyzed using [statistical test] with [assumptions tested]. The significance level was set at α = 0.05." -
Secondary Analyses
"Secondary analyses included per-protocol analysis, subgroup analyses for [prespecified subgroups], and sensitivity analyses [describe approaches]. Multiple comparisons were adjusted using [method]." -
Missing Data
"Missing data were handled using [method: complete case analysis/ multiple imputation/mixed-effects models]. Missing data patterns were examined and [describe findings]. Sensitivity analyses compared results across different missing data approaches."
Software and Methods
"Statistical analyses were performed using [software name and
version]. [Specific packages/procedures used]. All tests were
two-sided unless otherwise specified."
Examples:
- "Analyses were conducted using R version 4.3.0 (R Foundation
for Statistical Computing, Vienna, Austria)."
- "SPSS version 29.0 (IBM Corp., Armonk, NY) was used for all
statistical analyses."
- "DataStatPro version 2.1 was used for statistical analysis
and visualization."
Results Section Structure

Primary Outcomes
Continuous Outcomes
"The mean [outcome] was [X] (95% CI: [X] to [X]) in the
intervention group and [X] (95% CI: [X] to [X]) in the control
group. The between-group difference was [X] (95% CI: [X] to [X];
p = 0.XXX), representing a [clinical interpretation] effect."
Binary Outcomes
"[Outcome] occurred in [X] of [N] participants ([X]%) in the
intervention group and [X] of [N] participants ([X]%) in the
control group. The risk ratio was [X] (95% CI: [X] to [X];
p = 0.XXX), corresponding to a number needed to treat of [X]
(95% CI: [X] to [X])."
Time-to-Event Outcomes
"During a median follow-up of [X] [time units] (IQR: [X] to [X]),
[outcome] occurred in [X] participants ([X]%) in the intervention

Real-World Example: Clinical Trial Report
Study Context
Study: Randomized controlled trial of new antihypertensive drug
Design: Double-blind, placebo-controlled
Participants: 400 adults with hypertension
Primary outcome: Change in systolic blood pressure at 12 weeks
Methods Section Example
"This was a randomized, double-blind, placebo-controlled trial
conducted at 15 centers. Sample size was calculated to detect
a 5 mmHg difference in systolic blood pressure with 90% power
and α = 0.05, requiring 180 participants per group. To account
for 10% attrition, we planned to randomize 400 participants.
The primary analysis used intention-to-treat principles with
all randomized participants. Change in systolic blood pressure
from baseline to 12 weeks was analyzed using ANCOVA, adjusting
for baseline blood pressure, age, and sex. Missing data were
handled using multiple imputation with 20 imputations.
Secondary analyses used per-protocol populations and included
subgroup analyses by age (<65 vs ≥65 years) and baseline
severity. Statistical analyses were performed using DataStatPro
version 2.1, with significance set at α = 0.05."
Results Section Example
"Between March 2023 and September 2023, 400 participants were
randomized (200 per group). Baseline characteristics were
well-balanced (Table 1). Mean age was 58.3 years (SD = 12.1),
and 52% were male.
The primary endpoint showed a significantly greater reduction
in systolic blood pressure in the treatment group (-12.3 mmHg,
95% CI: -15.1 to -9.5) compared to placebo (-2.1 mmHg,
95% CI: -4.9 to 0.7). The between-group difference was
-10.2 mmHg (95% CI: -14.2 to -6.2; p < 0.001), exceeding
the prespecified clinically meaningful difference of 5 mmHg.
Secondary outcomes are presented in Table 2. Diastolic blood
pressure reduction was also significantly greater with treatment
(-7.8 vs -1.2 mmHg; difference -6.6 mmHg, 95% CI: -9.1 to -4.1;
p < 0.001). The treatment effect was consistent across prespecified
subgroups (Figure 2; all p-values for interaction > 0.10)."

Frequently Asked Questions
Q: How many decimal places should I use for p-values?
A: Generally 3 decimal places (p = 0.023). For very small p-values, use p < 0.001 rather than many decimal places.
Q: Should I report exact p-values or use significance thresholds?
A: Report exact p-values when possible, as they provide more information than just "significant" or "not significant."
Q: When should I include confidence intervals?
A: Always include confidence intervals for effect estimates. They provide information about precision and clinical significance.
Q: How do I report non-significant results?
A: Report them fully with effect sizes and confidence intervals. Avoid terms like "trend toward significance."
Q: What's the difference between statistical and clinical significance?
A: Statistical significance indicates the result is unlikely due to chance; clinical significance indicates the result is meaningful for patient care.
