We used backward elimination method with a P > 0.1 threshold for exclusion to construct the Model. The candidate variables for the Model were BOP, PCR, and ROM. The F-statistic was 8.744 (P-value was 0.001), the R-square was 0.580, and the adjusted R-square of the model was 0.514. The variance inflation factor was <5 and condition index was <15. represents differences (value at follow-up minus value at baseline). N: number, CI: confidence interval, B: unstandardized regression coefficient, β: standardized coefficient, CAL: clinical attachment level, BOP: bleeding on probing, PCR: plaque control record, CARR U: and Carratelli units. |
