Measurement error in clinical trials

Measurement error in clinical trials refers to inaccuracies or inconsistencies in how data—such as health measurements or test results—is collected. These errors can occur due to limitations of equipment, human mistakes, or other factors, leading to data that doesn't perfectly reflect the true health status or response of participants. Such errors can affect the accuracy of trial findings, potentially making it harder to determine whether a treatment is truly effective or safe. Recognizing and minimizing measurement error is important to ensure reliable and valid results in clinical research.
