TABLE 3.

Characteristics of PLWH stratified by undetected ( ≤ 50 copies/mL) or detected (>50 copies/mL) HIV plasma viral load (VL) at the post-HAART visit (visit 2).

Body mass index, kg/m 2 , mean (SD)	25.4 (4.0), n = 118	25.2 (3.8), n = 112	25.9 (4.2), n = 68	25.8 (3.7), n = 73
Smoking, cumulative pack years, mean (SD)	15.1 (21), n = 121	15.7 (21), n = 123	11.3 (18)	12.1 (19), n = 73

a: n = 125 for the undetected PLWH group, unless otherwise indicated.

b: n = 74 for the detected PLWH group, unless otherwise indicated; one PLWH missing HIV VL at visit 2 could not be assigned to a group and was excluded from these analyses.

c: p-values from Student’s t-tests for continuous variables and chi-squared tests for count data (p-values bold if <0.05).
