Synthesis of two studies presenting differences in mean OHIP total scores. Forest plots presenting differences in mean OHIP total scores of categories of number of present teeth for three samples (total n = 12,965) [25, 43]. The category 25-32 teeth was used as reference. Relative box size indicates the weight of the study: (a) 1-8 teeth (heterogeneity Q = 16.75; df = 2), (b) 9-16 teeth (heterogeneity Q = 17.80; df = 2), (c) 17-20 teeth (heterogeneity Q = 22.06; df = 2), (d) 21-24 teeth (heterogeneity Q = 15.51; df = 2).
