Geo-map of caries risk in adolescents. Caries risk geo-map of the Halland region (southwest Sweden) displaying, for each of the 66 residential parishes, the smoothed relative risk (SmRR, range between 0.75-1.20) of caries (dmfs/DMFS >0) among adolescents (12-19 years). The thicker borderlines delimit the six municipalities of Halland. The corresponding statistical certainty geo-map is also shown [red color, Pr(RR>1|data) > 0.95, i.e. a parish with data yielding strong statistical evidence of an elevated caries risk; green color, Pr(RR<1|data) > 0.95, i.e. a parish with data yielding strong statistical evidence of a low caries risk; and yellow color, the 90% credibility interval covers RR = 1, i.e. a parish with data yielding weaker statistical evidence for a high or low relative risk].
