Incidence and Predictors of Virologic Failure Among Children on First-Line Antiretroviral Therapy in Northwest Ethiopia: A Multicenter Retrospective Follow-Up Study.
Article in Journal of the International Association of Providers of AIDS Care. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BackgroundVirologic failure in children is a significant public health concern in sub-Saharan Africa. This study aims to assess the incidence rate of virologic failure and its predictors among children undergoing first-line antiretroviral therapy (ART) in Ethiopia.MethodsA multicenter retrospective follow-up study was conducted in HIV-infected children on first-line ART from January 1, 2013, to December 31, 2022, in Ethiopia. A simple random sampling method was employed to select the sample. Data entry was performed using EpiData, and analysis was conducted using STATA version 14. Kaplan-Meier curves and log-rank tests were utilized for survival analysis.ResultAmong 537 HIV-infected children followed over the study period, 12.29% developed virologic failure, yielding an incidence rate of 17 per 10 000 person-month observations (95% confidence interval [CI]: 13.4, 21.7). Factors independently associated with an increased risk of virologic failure included poor ART adherence (adjusted hazard ratio [AHR] = 2.63; 95% CI: 1.38, 4.97), advanced World Health Organization (WHO) Treatment (T) stages III and IV (AHR = 2.71; 95% CI: 1.15, 6.37), no history of regimen change (AHR = 5.88; 95% CI: 3.23, 10.71), and age at ART initiation above 10 years (AHR = 2.97; 95% CI: 1.30, 6.78). In contrast, having a caregiver younger than 40 years was associated with a significantly lower risk of virologic failure (AHR = 0.42; 95% CI: 0.25, 0.72). These findings emphasize the importance of monitoring adherence, providing closer follow-up for children in advanced treatment stages, and considering caregiver-related factors to reduce virologic failure.ConclusionsVirologic failure among HIV-infected children on first-line ART in Northwest Ethiopia was a relatively low incidence. Interventions targeting poor adherence, children with advanced WHO Treatment (T) stage, older age at ART initiation, and those with no history of regimen change are essential. Additionally, caregiver characteristics, such as age below 40 years, play a protective role and should be considered when designing adherence support and monitoring strategies to further reduce the risk of virologic failure.
