Data are percentages unless otherwise stated. Percentages were calculated out of column totals (N), except for ‘percentage of total’ where % refers to percentage of total sample in each oral health category. There were 4933 (2.86%) participants with missing data on number of own teeth left and 6831 (3.96%) missing data on self-rated heath of teeth and gums. Overall totals include the missing cases.
*Participants who rated their health of teeth and gums as ‘excellent’ (n=16,495, 9.6%) and those who rated their health of teeth and gums as ‘very good’ (n=46,481, 26.9%) are grouped together. All of the above baseline characteristics were significantly different according to tooth loss (p<0.0001) and according to self-rated health of teeth and gums (p<0.0001); χ2 tests were used to compare categorical variables; Kruskal–Wallis test was used to compare mean age.
