^*The numbers in the “Est” columns are slope values of the correlation between continuous covariates with MUCP, FUL or VLPP. However, for covariates that are categorical and not continuous, the numbers in “Est” column are not the slope, but rather the mean values of MUCP, FUL or VLPP for that particular covariate as denoted by the footnotes below.

¹These numbers represent mean FUL values for subjects with these stages of prolapse: Stage 0 and 1 (32.79 mm), Stage 2 (31.21 mm), Stage 3 and 4 (34.66 mm).

²These numbers represent mean FUL values for subjects with these categories of strength of PC contractions: No response (32.95 mm), Weak squeeze (31.32 mm), Moderate squeeze (32.50 mm), Strong squeeze (34.78 mm).

³These numbers represent mean MUCP values for subjects with no prior UI surgery (69.69 cm water) and prior UI surgery (56.50 cm water).

⁴These numbers represent mean VLPP values for subjects who underwent RMUS (114.05 cm water) and TMUS (124.67 cm water).
