Characteristics of registered and unregistered FSWs in Tijuana, Mexico (n=410)^a

^aThe first three columns of data are displayed by number (percent) of women and median (IQR) for dichotomous and continuous variables, respectively. Dichotomous outcomes were examined using Fisher's exact test. Continuous outcomes were examined using Wilcoxon's rank sum test for differences in group distributions. Certain percentages may reflect denominators smaller than the n-value given in the column head; these discrepancies are due to missing data.

FSW = female sex worker

IQR = interquartile range
