  1. Beta: Regression Coefficient; OR = Odds Ration; CI = Confidence Interval; aOR = Adjusted Odds Ratio.
  2. *Statistically significant (P-value < 0.05).
  3. †Due to colinearity between “receiving free condoms in the last 12 months” and “receiving free water-based lubricant in the last 12 months”, the independent variable “receiving free water-based lubricant in the last 12 months” was removed from the multiple logistic regression models due to lower number of observations. Note: Colinearity does not bias results, but it produces large standard errors in the related independent variables and an effective remedy for Colinearity is to drop an explanatory variable in order to produce a model with significant coefficient estimates for the remaining explanatory variables [14].
