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 and Aims: Despite the expanded availability of antiretroviral therapy (ART), HIV remains a major global health challenge. Viral load (VL) is the main indicator used to assess treatment response, and viral suppression is the ultimate goal of therapy. However, virological response is influenced by various patient- and treatment-related factors. This study aimed to identify factors associated with viral suppression among PLWH in Kermanshah, Iran. Methods: We included 2909 PLWH attending the Kermanshah Behavioral Diseases Counseling Center between 2012 and 2023. Data on demographic, behavioral, and clinical characteristics, route of transmission, disease stage, clinic visits, CD4 counts, and VL were extracted from records. Due to the non-normal distribution of VL, nonparametric tests (Spearman's correlation, Mann-Whitney Results: Among the 710 PLWH included in the analysis, 643 (90.6%) had viral suppression at the last available follow-up VL measurement (VL < 200 copies/mL). In univariate analyses, sex, incarceration history, addiction history, injection drug use, marital status, occupation, clinical stage, route of HIV transmission, CD4 count, and duration of ART were significantly associated with viral suppression. In the multivariable logistic regression model, marital status, clinical stage, baseline CD4 count, and follow-up CD4 count remained significantly associated with viral suppression after adjustment for the variables included in the model. Conclusion: Most PLWH had viral suppression at the last follow-up assessment. Disease stage, marital status, and follow-up CD4 count were associated with viral suppression. These findings should be interpreted with caution because residual confounding cannot be excluded. Overall, the results highlight the importance of early HIV diagnosis, timely initiation of treatment, and sustained engagement in care to achieve optimal viral suppression.
