Random-effects meta-regression analyses showed a decreasing trend in seroprevalence with higher income levels (coefficient ( C ) = –1.65 × 10 −6 ; p < 0.001), and HDI ( C = –0.4001; p < 0.001) ( Figs. 3 A,B).

Subgroup analysis of data at the beginning date of sampling showed an increasing trend of seroprevalence estimates on a monthly basis ( Table S4 ).
