We don’t know if most people actually stuck to their workout plans — only one study checked, so we can’t be sure the results reflect what really happened during training.
Scientific Claim
Training adherence was reported in only one of the five included studies, introducing potential bias in the interpretation of muscle hypertrophy outcomes due to unmeasured variability in program compliance.
Original Statement
“However, it also needs to be mentioned that adherence to the training programs was reported only in one study.”

The Effects of Low-Load Vs. High-Load Resistance Training on Muscle Fiber Hypertrophy: A Meta-Analysis
The study looked at different types of weight training but didn’t track whether people actually stuck to their workout plans, which could affect the results—so the claim that this missing info might mess up the conclusions is supported.
