Impact of optimized antiretroviral therapy on virological and nutritional outcomes among HIV infected adolescents in Cameroon.
Article in BMC pediatrics, 2026. 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
backgroundOptimization of antiretroviral therapy (ART) is one of the key recommendations of the World Health Organization (WHO) since 2019 to achieve 95% viral suppression. The transition to optimized therapeutic regimens (OTRs) in pediatrics began in Cameroon at 2020. The objective of our study was to evaluate the impact of OTRs on HIV-infected adolescents (HIA) in healthcare facilities in the city of Douala.
methodsA multicenter cross-sectional study was conducted from February to June 2022 in five hospitals in Douala. All HIA aged 10-19 years receiving ART for at least six months were included. Sociodemographic, clinical, therapeutic, and data related to the transition to optimized regimens were collected. Statistical analyses were performed using SPSS version 25. A p-value < 0.05 was considered statistically significant.
resultsOut of the 613 adolescents on antiretroviral therapy (ART), 599 (97.7%) were included in the study at a median age of 15 years (interquartile range [IQR]: 13-18 years). The male-to-female ratio was 0.9, and most adolescents (94.0%) had acquired HIV through mother-to-child transmission. Among the 599 HIV-infected adolescents (HIV), 391 (65.3%) were receiving optimized therapy, with a mean ART duration of exposure of 11.6 ± 5.7 months. Before switching to optimized therapy, 329 adolescents (84.2%) had viral suppression, compared to 370 (94.6%) after switching. Adolescents receiving optimized antiretroviral therapy were significantly 3.3 times more likely to have viral load suppression (OR: 3.3; 95% CI: 2.0-5.6; p < 0.001). These optimized regimens significantly reduced moderate malnutrition (OR: 0.38; 95% CI: 0.16-0.91; p = 0.042) and improved nutritional status, with mean weight increasing from 43.2 ± 13.0 kg to 46.7 ± 13.3 kg (p < 0.001) and body mass index increasing from 18.8 ± 3.2 to 19.6 ± 3.0 kg/m² (p < 0.001).
conclusionOptimized antiretroviral regimens significantly improved viral suppression and moderate malnutrition among HIV infected adolescents in Douala, Cameroon.
