Notes:
*
The difference was statistically significant.
a
The covariables that need to be adjusted in multivariable linear regression are start year, language, region, publisher and journal size.
b
GR (95% CI): geometric means ratio (95% confidence interval), this value is calculated by using the “not endorsed” group as the reference group. For example, GR = 1.652 says that the number of citations is 65.2% higher for journals that endorse RCT registration, the same is true for other results.
