What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Sichuan Province was severely affected by the HIV, and there was a scarcity of data regarding the survival time and influencing factors for People Living with HIV/AIDS (PLWH) in Sichuan Province who have received Antiretroviral Therapy (ART). Therefore, it is necessary to conduct a survival analysis for PLWH receiving ART. Methods: A retrospective cohort study was conducted on PLWH who had received ART≥6 months in Sichuan Province from January 1, 2003, to December 31, 2022. The Kaplan-Meier method was used to calculate median survival time and plot survival curves, while a Cox proportional hazards regression model was applied to analyze factors affecting survival time. Bilateral tests were performed, with P≤0.05 considered statistically significant. Results: The cumulative survival rates at 1, 3, 5, and 10 years for the 223,386 subjects were 94.54%, 89.07%, 84.82%, and 76.44%, respectively. Multivariate analysis using the Cox regression model indicated lower mortality risks for females (HR=0.59, 95% CI: 0.54-0.65), homosexual transmission (HR=0.43, 95% CI: 0.33-0.55), and baseline BMI≥24 (HR=0.81, 95% CI: 0.72-0.90). Higher mortality risks were associated with age≥50 years at diagnosis (HR=3.21, 95% CI: 2.94-3.50), being unmarried or divorced (HR=1.23, 95% CI: 1.11-1.37), living separately (HR=1.32, 95% CI: 1.22-1.43), baseline BMI <18.5 (HR=1.27, 95% CI: 1.13-1.41), presence of single-drug resistance (HR=1.25, 95% CI: 1.15-1.36), baseline WHO stage IV (HR=1.27, 95% CI: 1.09-1.47), and a diagnosis-to-treatment interval >12 months (HR=1.27, 95% CI: 1.15-1.41). Compared to those with CD4(+) T cell count of 200-350cells/μL, 350-500cells/μL, and >500cells/μL at baseline, individuals with <200cells/μL had higher mortality risks (HR=0.73, 95% CI: 0.67-0.79; HR=0.57, 95% CI: 0.51-0.64; and HR=0.58, 95% CI: 0.51-0.66, respectively). Conclusion: The survival rate for PLWH receiving ART in Sichuan Province was relatively high. Male gender, age over 50 at diagnosis, being unmarried, divorced, or living separately, presence of single-drug resistance, low baseline BMI, baseline CD4+ T cell <200cells/μL, baseline WHO stage IV, and a diagnosis-to-treatment interval >12 months were risk factors for the survival of PLWH.
