Periodontal parameters (all measures pooled) in OC cases vs controls · Adults in case-control studies (oral cancer patients vs healthy controls)
Pooling all periodontal measures, oral cancer patients had worse periodontal status than controls (SMD 0.95, 95% CI 0.41-1.49; very high heterogeneity, I2=96.8%); ungraded. Note this pools clinically different measures.
