Osteoarthritis and mechanical versus metabolic improvement

Osteoarthritis and mechanical versus metabolic improvement Writing it up because I had to work it out twice and would rather nobody else did.

Asking about a population rather than about a person.

The published trials in this class mostly enrolled a fairly specific group, and the questions here frequently come from people well outside it. I would like to understand what the honest position is when someone falls outside the studied population: not "it is fine" and not "there is no data", but what the reasoning actually looks like.

the opening post answers the question as asked. The question underneath it is different.

Hepatic steatosis and MASH: a phase 2 trial in semaglutide for steatohepatitis showed resolution was more frequent on treatment. Histological resolution is a surrogate for long-term clinical outcomes like cirrhosis.

Cardiovascular disease: several compounds have cardiovascular outcome trials. SELECT was in people without diabetes; SUSTAIN 6 was in high-risk diabetes. Absolute benefit is largest in high-risk people.

Obstructive sleep apnoea: SURMOUNT-OSA used an objective endpoint, the apnoea-hypopnoea index. Reduction was substantial. Whether the benefit is weight loss or a direct drug effect is not resolved by the trial.

Worth separating two things that the opening post runs together.

Bariatric surgery history: altered anatomy after surgery affects absorption. That matters for oral medications and for reconstituted solutions. Discussing specific medications and doses with a clinician familiar with bariatric surgery is prudent.

I disagree with the reply above, and I think the disagreement is substantive rather than terminological.

The distinction being drawn does not survive when you look at the published data for this specific question. I would be glad to be shown wrong on this, because the version I am arguing against is more convenient.

Interactions between comorbidities: diabetes and kidney disease together change the risk calculation for hypoglycemia and for medication clearance. They are not independent variables.
