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
introductionBictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) is a preferred antiretroviral regimen in international guidelines, but long-term real-world data in Latin American people living with HIV (PLWH) are scarce. This study describes 48-month persistence, virological effectiveness, safety and metabolic changes in the Argentine BICTARG cohort. MATERIAL AND
methodsWe conducted an observational, retrospective, open cohort study including treatment-naïve (TN) and treatment-experienced (TE) adults with HIV who initiated B/F/TAF between October 2019 and December 2022 at a large HIV centre. Persistence on B/F/TAF, virological suppression (VS, <50 copies/mL), B/F/TAF-related adverse events (AEs), and metabolic parameters (fasting glucose, cholesterol, and triglycerides) were assessed at 24, 36 and 48 months.
resultsOverall, 3,057 PLWH were included: 425 TN (14%) and 2,632 TE (86%). In TN, persistence at 24, 36 and 48 months was 99%, 97% and 95%, and VS rates were 95%, 93% and 90%, respectively, with no AEs reported. In TE, persistence was 98%, 96%, and 88%, and VS rates were 96%, 98%, and 98%; AE rates were ≤0.4%, with no virological failure. Fasting glucose remained unchanged; TN participants showed increases in total, LDL, and HDL cholesterol, whereas in TE participants, lipid levels were stable and triglycerides decreased over time (p<0.001).
conclusionsIn this large Argentine cohort, B/F/TAF demonstrated high persistence, sustained VS, low AE rates and an overall favourable metabolic profile over 48 months in both TN and TE PLWH, providing the first long-term real-world evidence from Latin America.
