Multivariable logistic regression with inverse probability censoring weighting assessed the association between the number of residual sites with PPD \u2265\u20095\u2009mm at the start of SPC and disease progression at 1\u2010year and 5\u2010year intervals.

For periodontal tooth loss, each additional PPD \u2265\u20095\u2009mm site increased the odds by 11% over 5\u2009years.
