CI: Confidence Interval; IRR: Incidence Rate Ratio.
^aMaximum Possible Score for the Overall Quality of Reporting Score = 14.
^bThe sample size variable was log(10) transformed. The value is an expression of the change in the average of the OQRS due to one unit increase in sample size in the log scale.
