Owing to rounding of the percentages, total sums are not always exactly 100%.
Total sums up to >28 and >35 patients, because some patients had both oral complaints currently and during the last 3 months.
Total sums up to >28 and >35 patients, because some patients had both acute and chronic oral foci of infection.
Total sums up to >24 and >22 patients, because some patients had more than one type of chronic oral foci of infection.
The difference between the groups is significant (P=0.024) using a Mann–Whitney test.
Plaque and bleeding scores were given as an estimated percentage of the total number of measured sites, after probing periodontal pockets.
The difference between the groups is not significant (P=0.56) using a Mann–Whitney test.
The difference between the groups is significant (P=0.005) using a Mann–Whitney test.
