Notes for the correlation coefficient ranking of Spearman’s ρ (p < 0.01): NES, negative and extremely strong; NS, negative and strong; NM, negative and moderate; NW, negative weak; None, not significant; PW, positive and weak; PM, positive and moderate; PS, positive and strong; PES, positive and extremely strong; N5, negative correlation (p < 0.05); P5, positive correlation (p < 0.05). ** indicates that the correlation is significant when the confidence (double test) is 0.01; * indicates that the correlation is significant when the confidence (double test) is 0.05. CCC0126 denotes the number of cumulative confirmed cases on 26 January 2020, and the like. tMean denotes the average of the cumulative confirmed COVID-19 cases from 26 January to 18 February 2020. MINE denotes minimum elevation. MAXE denotes maximum elevation. MNE denotes the mean of elevation. RAE denotes a range of elevations. LA denotes land area. PD denotes population density. RGP denotes registered population. RSP denotes the resident population. TRS denotes the total retail sales of consumer goods. Moreover, GDP denotes regional gross domestic product.
