People in the FEAST study who have knee arthritis are pretty much like people in four other big studies around the world — so what they found in FEAST probably applies to most adults with knee arthritis too.

Assessment Explanation
The claim describes a comparison of baseline characteristics across cohorts, which is a descriptive analysis commonly performed in epidemiological and clinical research. It does not imply causation or mechanism, and the use of 'comparable' is appropriately cautious. The claim correctly frames generalizability as a conclusion drawn from similarity in baseline data, which is standard practice. No overstatement is present, as it does not claim the findings are universally applicable, only that comparability supports generalizability.
More Accurate Statement
“The baseline characteristics of adults aged 45–85 with knee osteoarthritis in the FEAST cohort are similar to those in four large international cohorts, suggesting that findings from the FEAST cohort may be generalizable to similar populations.”

The eFEct of an Anti-Inflammatory Diet for Knee oSTeoarthritis (FEAST) Trial: Baseline Characteristics and Relationships With Dietary Inflammatory Index.
The study didn’t test whether the diet works, but it did check if the people in the study looked like people in other big studies around the world — and they did. So yes, the findings can be trusted to apply more broadly.
