Fisher’s exact test.

Wilcoxon rank sum test.

Frequency of urination, properties of urine samples, and constituent results were assayed for associations with participant-reported vaginal intercourse. Any outcome other than “negative” was considered a positive urine test result, except for specific gravity and pH data, which do not have “negative” outcomes. P values are shown in the table. The chi-square test was used unless otherwise indicated. P values of <0.05 represent statistical significance (bold). n, number of participants. Data corresponding to properties and constituents for a given participant that were always negative or baseline are represented by empty cells (or by “N/A”). N/A (not applicable), participant did not report vaginal intercourse. Significant P values that are underlined represent urine properties and constituents with “positive” results found at higher frequencies (or higher mean values) following vaginal intercourse. The numbers in parentheses in each applicable cell represent the number of times each “positive” categorical test result was coreported with vaginal intercourse in the total number of reports. Vaginal intercourse was reported as follows: for ProFUM01, 0/67 days; for ProFUM02, 2/66 days; for ProFUM03, 0/71 days; for ProFUM04, 27/72 days; for ProFUM05, 21/67 days; for ProFUM06, 1/66 days; for ProFUM07, 4/69 days; for ProFUM08, 3/67 days.
