Sex-stratified analysis showed a trend toward higher ISS in men (median 4.0, IQR 1.0–5.0) than in women (median 3.0, IQR 1.0–4.0; p = 0.078, Wilcoxon rank-sum test).

A highly significant heterogeneity in incidence rates was observed across the three catchments (likelihood ratio test, χ 2 with 2 degrees of freedom, p < 2.2 × 10− 1 6), indicating that incidence rates were not homogeneous between areas.
