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
backgroundAntiretroviral therapy (ART) has revolutionized the management of human immunodeficiency virus (HIV) infection by transforming it into a chronic but manageable condition. Despite its effectiveness in viral suppression and immune restoration, concerns remain regarding ART's potential impact on cardiovascular health, particularly on electrocardiographic (ECG) parameters.
objectiveThis study investigated the effects of ART on ECG parameters in HIV-infected patients by analyzing pre- and post-therapy data.
methodsA total of 83 HIV-positive patients were enrolled and evaluated for ECG parameters before and 3 months after ART initiation. Key parameters, including QRS duration, QT duration corrected by the Bazett formula (QTc interval), QRS-T angle, morphology in inferior leads, voltage in lead 1, and P-wave duration (MVP) score, were manually assessed. Statistical analyses compared pre- and post-ART values.
resultsNo statistically significant changes were observed in ECG parameters post-ART. For example, QRS duration remained stable (pre-ART: 89.08 ± 12.01 ms; post-ART: 88.94 ± 10.00 ms, p = 0.849), as did QTc interval (pre-ART: 403.51 ± 22.22 ms; post-ART: 404.84 ± 14.91 ms, p = 0.563) and MVP ECG score (pre-ART: 3.02 ± 0.95; post-ART: 2.98 ± 0.87, p = 0.882). The QRS-T angle also showed no significant difference (p = 0.675).
conclusionART does not appear to significantly affect ECG parameters in HIV-infected patients, supporting its favorable cardiac safety profile. These findings highlight the importance of regular ECG monitoring to ensure cardiovascular safety in patients undergoing ART.
