Survival Analysis of PLWHA in China

The data used in the present study were extracted from 1,694 PLWHA from the China Disease Prevention and Control Information System (CDPCIS) during 17 years of follow-up in the Huzhou area, China. Detailed information on participant enrollment, HAART, and follow-up can be found in a previous study (17 (link)). The inclusion criteria were as follows: over 18 years of age; living in the Huzhou area containing temporary residents; diagnosed or identified from 1 January 2005 to 30 June 2022; having completed baseline (pre HAART) laboratory serum testing; and being visited at least once. Survival time was determined as the duration from receiving HAART to death or 30 June 2022. PLWHA who received HAART before entering the cohort, those with missing baseline hemoglobin records, or those with illogical survival times were excluded from the final data analysis.
Among the 1,694 PLWHA enrolled in this study (Figure 1), 169 were excluded based on the inclusion criteria. Of the remaining 1,525 participants, 96 were dead and 1,429 were alive.
