The only glucose outcome after treatment is FASTING serum glucose, 10.98 to 6.71 mmol/L within the fenugreek group (paired t-test vs its own baseline, p = 0.001); the untreated diabetic control also drifted 11.53 to 10.6. The OGTT was run only to confirm diabetes before treatment. Postprandial effects are inferred solely from in-silico docking: compounds 'having a strong binding affinity to alpha-glucosidase, which suggests ... supplements might control postprandial blood glucose levels.' No postprandial measurement; claim object not measured. |

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
