Question · asked by 1 review
Chlorhexidine mouthrinse (any concentration; 0.05% to 0.2%) used in conjunction with mechanical oral hygiene procedures vs Placebo/control mouthrinse, or no mouthrinse (mechanical oral hygiene alone); controls pooled (protocol's separate comparisons versus mechanical oral hygiene alone and versus placebo/control merged): Supragingival calculus formation (various calculus indices)

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
