Study Design Types

🎯

RCT

Randomized Controlled Trial

Gold standard for causal inference. Random allocation eliminates confounding. Best when: ethical equipoise exists and blinding is feasible. Watch for: attrition, non-compliance, generalizability.

📊

Cohort

Prospective / Retrospective

Follow exposed vs unexposed over time. Can estimate incidence and relative risk. Ideal for rare exposures. Watch for: loss to follow-up, confounding, time-varying exposures.

🔍

Case-Control

Retrospective Comparison

Compare cases to controls on past exposures. Efficient for rare outcomes. Estimates odds ratios. Watch for: selection bias, recall bias, appropriate control selection.

📸

Cross-Sectional

Point-in-Time Snapshot

Measure exposure and outcome simultaneously. Good for prevalence, hypothesis generation. Cannot establish temporality. Watch for: prevalence-incidence bias, temporal ambiguity.
