  1. CI: Confidence Interval; IRR: Incidence Rate Ratio.
  2. aMaximum Possible Score for the Overall Quality of Reporting Score (OQRS) = 14.
  3. bMaximum Possible Score for the Key Methodological Items Score = 3.
  4. cThe 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.
  5. No individual analysis of the Intervention (I) component of the PICOT score was done because all studies reported their intervention when they described their research question.
