^aNumber of P. gingivalis-positive patients. 

^bSignificant differences (P < 0.05) were found for the following comparisons: type II versus type I, III, IV, I-II, and II-IV, and untypeable infections; 4-mm versus 8- to 15-mm pocket probing depth male versus female sex; and age 24 to 35 years versus age 36 to 57 years for females. 

^cUT, untypeable.
