Table 4.
Spearman’s rank correlation coefficients and 95% confidence intervals (CI) between self-report measures of drinking and PEth concentration overall, and among current drinkers only, for 209 HIV-infected adults, who participated in the BREATH Cohort study (July 2011-September 2013) at the Immune Suppression Syndrome Clinic in Mbarara, Uganda. The table shows coefficients and 95% CIs for the correlation of FGF measures, QF measures, and two screeners, that is, AUDIT-C and number of drinking days with PEth.
