Health Outcomes Statistical Analysis Protocol Development
Design FDA-compliant statistical protocols for health outcomes studies
What You Can Do
Create comprehensive statistical analysis plans (SAPs) that meet regulatory standards for health outcomes research. You can generate protocol frameworks, validate statistical methods, calculate power requirements, and produce reproducible analysis workflows with full documentation for FDA submissions, clinical trials, and real-world evidence studies. The skill ensures your analyses are auditable, replicable, and compliant with ICH-GCP and regulatory guidance.
Features
Automatically creates comprehensive SAPs specifying primary/secondary endpoints, statistical methods, analysis populations, hypothesis frameworks, and success criteria aligned with regulatory standards.
Validates your study design and analytical approach against FDA, ICH-GCP, and international health authority guidelines to ensure submissibility and audit readiness.
Calculates required sample sizes and statistical power for your primary outcome using appropriate effect sizes, significance levels, and multiplicity corrections with sensitivity analysis.
Produces fully annotated R and Python scripts for primary, secondary, and sensitivity analyses that can be version-controlled, audited, and re-executed to verify results.
Documents missing data strategies, assumption violations, and pre-specified subgroup analyses to strengthen study credibility and demonstrate robustness to regulators.
Maps your protocol to reporting standards (CONSORT for RCTs, STROBE for observational studies) ensuring transparent, complete reporting aligned with publication norms.
Evaluates proposed statistical tests for appropriateness given study design, outcome type (continuous, binary, time-to-event), and data characteristics with assumption diagnostics.
Creates auditable records of protocol modifications with justification narratives and impact assessments for regulatory submissions and data safety monitoring boards.
Example Output
Statistical Analysis Plan Output
Primary Endpoint Specification:
- Outcome: Time to clinical improvement (days)
- Population: Intent-to-Treat (N=280)
- Test: Kaplan-Meier + Cox proportional hazards regression
- Significance: α=0.05 two-tailed
- Power: 90% to detect hazard ratio of 1.6
Analysis Code (R):
library(survival)
fit_km <- survfit(Surv(time_days, improved) ~ treatment, data=trial_data)
fit_cox <- coxph(Surv(time_days, improved) ~ treatment + age + baseline_severity,
data=trial_data)
print(summary(fit_cox))
Sensitivity Analyses:
- Multiple imputation (MCAR, MAR, MNAR scenarios) for 12% missing outcomes
- Per-protocol population analysis (80% adherence threshold)
- Landmark analysis at 4, 8, 12 weeks
Regulatory Alignment:
- ✓ FDA E9 Statistical Principles (ICH-GCP compliant)
- ✓ STROBE checklist items 12a-b (analysis methods)
- ✓ Missing data handled per FDA 2021 guidance
- ✓ Multiplicity controlled (no α inflation)
What's Included
- Statistical Analysis Plan Template: Pre-structured SAP document with sections for study populations, endpoint definitions, hypotheses, statistical methods, multiplicity adjustments, and missing data strategies.
- Regulatory Compliance Checklist: FDA/ICH-GCP compliance verification matrix highlighting requirements met, gaps identified, and remediation steps for regulatory submission readiness.
- Power Analysis Workbook: Interactive sample size calculations, power sensitivity analysis, and assumption justification narratives with supporting references.
- Reproducible Analysis Scripts: Production-ready R and Python code with inline comments, validation diagnostics, and version control guidance for audit trails.
- Reporting Standards Mapping: Cross-references between protocol sections and CONSORT/STROBE checklist items ensuring transparent, guideline-compliant reporting.
