Spearman's rank correlation test (r, significance score of p value).
The first row represents correlation between the meteorological variable and clinical cases (CC) incidence. The second row represents correlation with biologically confirmed cases (BCC) incidence.
Significance score: *p<10−2, **p<10−3, ***p<10−4.
FXI, wind strength; GLOT, global brilliance; INST, sunstroke average; Lag2wk, lag 2 weeks; RR, cumulative rainfall; TN/TX, minimum and maximum temperature; UN/UX, minimum and maximum relative humidity.
