Analyzing Support for Pain Reduction Claims

In a recent study, researchers examined the effects of a new drug, Drug A, on patients with chronic pain. Researcher X argues that Drug A significantly reduces pain levels as compared to placebo treatment, based on a controlled trial that reported a 40% average reduction in pain over eight weeks. In contrast, Researcher Y asserts that the study had limitations, including a small sample size and short duration, suggesting that the observed effects might not be generalizable to the broader population. Which researcher's viewpoint remains stronger based on the arguments presented?
