Sensitivity Analysis: Mixed Effects Logistic Regression model assessing time since last HIV testing adjusting for patient, healthcare, and combined factors and the odds of HIV test completion, 2016–2017

aOR= Adjusted Odds Ratios; CI=Confidence Intervals; STI=Sexually transmitted infection
A Mixed Effects Logistic Regression model was used including all variables above after considering hierarchical structure of STI related visits by clinic and individual.
