  1. ap < 0.001, bp < 0.01, cp < 0.05, dp approached the significance < 0.05. CD4 count < 200 cells/mL was not included because it was insignificantly associated with physical health summary scores (p = 0.566). Years since starting ART was excluded because of co-linearity with the variable, years since HIV diagnosis. *Further multivariable linear regression models were performed for each basic need, estimated coefficient (β) unmet needs: food = −3.65, clothing = −3.72, housing cost = −3.67 (all, p < 0.001) or risk of homelessness = −1.04 (p > 0.05)
