For pairwise comparisons: one symbol=p<0.05; two symbols=p<0.01; three symbols=p<0.001.
*P<0.05; **p<0.01; ***p<0.001 for generalised linear mixed models testing for significant differences by most common funding source.
†Mann-Whitney U was used to test for significant differences in LMICs versus HICs.
‡Respondents did not provide information on funding source for CR in 9/335 surveys.
§Significantly different from all funding sources (p<0.001).
HIC, high-income country; LMIC, low/middle-income country.
