Race-stratified laboratory measurements for polycystic ovary syndrome (PCOS) algorithm cases and controls. Box plots of A, body mass index (BMI) measurements; B, insulin levels; C, estradiol levels; and D, free testosterone levels of race stratified PCOS algorithm data sets. Each color corresponds with a race. Boxes represent the 25th and 75th quartiles. Lines above and below the boxes represent the 95th and fifth quartiles. Lines within each box mark the median. Wilcoxon rank sum tests were performed between algorithm cases and controls within each race. Brackets display the P values of the statistical test. CB, coded broad; CN, controls; CS, coded strict; RB, keyword broad; RS, keyword strict.
