HIV vertical transmission linked to virological failure in pregnant women on ART.
Article in AIDS research and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundIn Ethiopia, where vertical transmission (VT) of HIV remains high, this study investigates the impact of maternal virological failure (VF) on VT outcomes.
methodsA retrospective cohort of 541 HIV-positive pregnant women from three high-prevalence hospitals was analyzed using bivariable and multivariable logistic regression.
resultsMultivariable logistic regression revealed that maternal VF was strongly associated with VT of HIV. Mothers with VF were nearly ten times more likely to transmit HIV to their infants compared to those with viral suppression (AOR = 9.96; 95% CI 3.19-31.11; p < 0.001). Additional independent predictors of VT included ART initiation during pregnancy (AOR = 3.54; 95% CI 1.48-8.48; p = 0.005), baseline CD4 count ≤ 350 cells/mm3 (AOR = 5.66; 95% CI 2.67-12.00; p < 0.001), poor ART adherence (AOR = 8.09; 95% CI 3.09-21.24; p < 0.001), and absence of infant nevirapine prophylaxis (AOR = 6.54; 95% CI 2.42-17.69; p < 0.001).
conclusionMaternal VF was strongly associated with increased risk of VT. These findings highlight the importance of early initiation of ART, consistent viral suppression, adherence support, and routine viral load monitoring as key strategies to reduce VT, particularly in high-burden settings. Strengthening these interventions may help target the small subset of mothers at highest risk and improve overall prevention outcomes.
