  1. *Shows data which had slight variations between our data calculations and the calculations made in the study, possibly due to a different method for calculating 95% confidence intervals.
  2. Shows data that produced significant differences in between our calculated data and the study’s data or it was not possible to calculate sensitivity and specificity from the data in the study
