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
introductionRetention to antiretroviral therapy (ART) is critical for controlling HIV/AIDS and reducing mortality rates worldwide. In Brazil, although ART is widely accessible, challenges remain in retaining individuals on treatment over time. This study aims to analyze trends in ART retention from 2014 to 2022, addressing gaps in current national data.
methodsThis is a population-based, cross-sectional study, that utilized data from the Brazilian national ART monitoring system to assess retention rates at 6-, 12-, 24-, 36-, 48-, and 60-months post-ART initiation. The analysis included individuals aged 15-years or older, with retention defined as no more than a 28-day delay in drug distribution. Descriptive analyses of retention from 2014 to 2022 were conducted using R version 4.0 (R Core Team, 2020) and SPSS version 21 (IBM Corp.)
resultsThe study observed over 3.4 million ART distributions, revealing that retention rates steadily declined over time, with the lowest rates observed at 60-months (71% in 2022). Men had consistently higher retention rates compared to women (79% vs. 73% in 2022). Lower retention was found among younger age groups (74% in 2022), indigenous populations (67% in 2022), individuals with lower education levels (72% in 2022), and those residing in northern (74% in 2022) regions of Brazil.
conclusionsThe study highlights considerable retention challenges, particularly after extended periods on ART, with notable disparities across demographic and regional groups. The findings suggest the need of interventions to improve ART retention, especially among vulnerable populations, to reach the 95-95-95 targets in Brazil. The introduction of multi-month drug dispensing and other strategies implemented during the COVID-19 pandemic may have helped stabilize retention rates in recent years.
