*Overall N = 192 with 13 participants missing mental health data, 11 missing VACS index;
aUnivariate Poisson regression models were used to estimate rates of hospitalisation and ER visits per person-year and incidence-rate ratios with 95% confidence intervals. In each model, follow-up time was used as an exposure to account for censoring due to lost to follow-up or death; bText in bold indicates statistically significant results;
cAdjusted models include adjustment for VACS index, substance use and mental health conditions.
dVACS index includes age, gender, race, CD4 count, viral load, markers of comorbidities.
