Values plotted against the probability of identifying severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection at universal testing. Solid lines indicate the predicted probability of infection from bivariable logistic regression models; shaded areas, 95% confidence bands. For each independent variable, circles are plotted at the mean values of the women residing in 10 equal-width bins. The circle size is proportionate to the number of women within each bin. Since bins may contain no patients, there are fewer than 10 circles in some panels. Interdecile range indicates 10th and 90th percentiles. The probability (and 95% CI) of SARS-CoV-2 infection for women at the 10th and 90th percentile of each independent variable was predicted from the regressions shown in each panel.
