In the original article, there was a mistake in Table 3 “The sensitivity (Se), specificity (Sp), positive predictive value (PPV), confidence intervals (CI), negative predictive value (NPV), likehood ratios +'ve (LR+) and likehood ratios –'ve (LR-) for predicting ovulation within 24 h at 15, 20, 25, 30, 35, and 40 mIU/ml thresholds on the 11th day of the cycle”. Upon review of the tables prior to a journal club, it was noted that there were some numerical values that had been inadvertently misplaced under the wrong columns when updating different previously edited tables. The corrected Table 3 appears below.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
Table 3. The sensitivity (Se), specificity (Sp), positive predictive value (PPV), confidence intervals (CI), negative predictive value (NPV), likehood ratios +'ve (LR+) and likehood ratios −'ve (LR−) for predicting ovulation within 24 h at 15, 20, 25, 30, 35, and 40 mIU/ml thresholds on the 11th day of the cycle.
