Backward Elimination : All independent variables are entered into the equation first and each one is deleted one at a time if they do not contribute to the regression equation.
B, beta estimator; S.E., standard error; β, standardized coefficient; VIF, variance inflation factor; GBR, guided bone regeneration; SPT, supportive periodontal therapy.
