*P<0.05, **P<0.01, when testing hypothesis that coefficient is equal to 0.

†P value from Chow test for the equality of coefficients between HIC and UMIC vs LMIC and LIC groups.

HIC, high-income countries; LIC, low-income countries; LMIC, lower-middle-income countries; UMIC, upper-middle-income countries.
