Periodontitis vs Individuals without periodontal disease (by LOA): Malignant transformation (oral cancer development)

Population
Adults in case-control studies of oral cancer; people assessed for periodontitis
Intervention
Periodontitis
Comparison
Individuals without periodontal disease (by LOA)
Outcome
Malignant transformation (oral cancer development)

Periodontitis is associated with roughly a threefold higher odds of oral cancer (pooled OR 2.94, 95% CI 2.13-4.07; low certainty of evidence), though heterogeneity is moderate (I2=52.4%).

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.
