Healthcare Utilization Unchanged in the Control Arm of a Randomized Clinical Trial.

ABSTRACT:

Background

In low-income settings, clinical trial participation may influence participant behavior, including among control groups. Increased access to care and heightened health awareness during trial enrollment could lead to altered behaviors, a phenomenon known as the Hawthorne effect, which may obscure true intervention impacts; however, this effect remains poorly studied in low-income environments.
