Ahmed works at the two ends of a study that decide whether anyone believes it: how the evidence is put together, and how it is explained afterwards.

The first is co-authorship on five systematic reviews and meta-analyses across gastroenterology, cardiology, rheumatology and neurology. Screening, extraction, risk of bias, pooled analysis, and the argument about what a pooled estimate is and is not allowed to say. Three of the five are indexed in PubMed, and one was presented at the American Heart Association Scientific Sessions and published in Circulation. Every one is listed on his ORCID record with a DOI, which is the point: you do not have to take the claim on trust, and on this site you should not have to.

The second is the writing. Manuscripts, protocols, methodology explanations, and the site you are reading now. A new research practice is judged on how it explains itself long before anyone sees its analyses. What a study claims, how carefully it is worded, and whether the limitations are stated plainly are editorial decisions with methodological consequences. Getting them wrong makes sound work look careless. Getting them right makes careful work legible to reviewers, editors and clients who have never met you.

He is a physician by training and works clinically. That is what keeps the methodology honest: an outcome that is statistically convenient and clinically meaningless is easy to miss from outside medicine and hard to miss from inside it.
