How this study scored 46/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on strength of evidence, so that was left out: it earned 44 of the 95 points we could judge it on, which is 46 out of 100.
