Certainty geo-maps of elevated/lowered relative risk of caries in 3-6-years old children; parishes with evidential, positional changes in caries risk indicated with connecting lines. Statistical certainty geo-maps of the Halland region (southwest Sweden) in 2006 and 2010, respectively, for each of the 66 residential parishes [red color, Pr(RR>1|data)>0.95, i.e. a parish with data yielding strong statistical evidence of an elevated caries (dmfs>0) risk; green color, Pr(RR<1|data)>0.95, i.e. a parish with data yielding strong statistical evidence of a lowered caries risk; and yellow color, a parish with data yielding weaker statistical evidence for a high or low relative risk]. The thicker borderlines delimit the six municipalities of Halland. The eight parishes with evidential, positional changes in caries risk are indicated with connecting lines providing information on changes in the smoothed relative risk (SmRR) and certainty rank (between 2006 and 2010).
