Consistent condom use with most recent non-paying partner	31.1 (68)
Consistent condom use with husband/cohabiting partner	9.6 (40)

¹Not all of the outcomes have the same denominator, as the sample was subset to women with different types of partners for each outcome; condoms used in all occasions of sexual intercourse with clients in the most recent day worked has a smaller denominator than consistent condom use with all occasional clients because of missing data in the former outcome.

²Consistent condom use is defined as reporting always (100%) using condoms.

³The total N for each factor may not add up to 775 due to missing values.
