Erratum

It has been brought to our attention that the last statement in the Results section of the Abstract of this article [1] is incorrect. This currently reads as: “Multivariate regression analysis, revealed that year of publication (t 32 = 5.17, p = 0.000, 95 % CI: 0.76, 1.76), and sample size (t 32 = 3.01, p = 0.005, 95 % CI: 1.36, 7.02), were the only two factors associated with reporting quality”. The error is the test statistic for the year of publication. It should be: “Multivariate regression analysis, revealed that year of publication (t 32 = 1.26, p = 0.000, 95 % CI: 0.76, 1.76), and sample size (t 32 = 3.01, p = 0.005, 95 % CI: 1.36, 7.02), were the only two factors associated with reporting quality”.
