Note. K, number of rs; N, total sample size; r_c, overall weighted mean of r corrected for sampling error only; r_p, overall weighted mean of r corrected for sampling error and measurement error of the field tests;

^a95% confidence interval;

^b95% credibility interval;

^cPercentage of variance accounted for by statistical artefacts including sampling error and measurement error of the field tests.
