HIV-1 suppression and rare dolutegravir resistance in antiretroviral-experienced people with HIV in Liberia.
Article in Communications medicine, 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
backgroundIncreasingly, persons with HIV in Liberia are receiving antiretroviral therapy containing the integrase strand-transfer inhibitor (InSTI) dolutegravir (DTG), but the prevalence of and factors associated with virologic failure and HIV drug resistance (HIVDR) remain unknown.
methodsCross-sectional analysis of 2019-2022 enrolment data from 1276 persons with HIV in the HONOR cohort included sociodemographic information, plasma viral loads (pVL), CD4 counts, and HIVDR testing by next generation sequencing in participants with virologic failure (pVL≥1000 copies/mL).
resultsOf the 1201 participants with pVL results, 72% are female and median age is 42 (interquartile range [IQR] 35-50) years. All are on ART (median 6.1 [2.1-11] years): 74% on DTG-based and 23% on non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens. Ninety (7.5%) had virologic failure; 970 (81%) are suppressed (<40 copies/mL). Virologic failure is less prevalent with DTG- versus NNRTI-based regimens (5.3% vs. 14%, adjusted prevalence ratio [aPR]=0.3, 95% confidence interval [CI] 0.2-0.5) and is associated with age <50 years, CD4 count <200 cells/µL, and hemoglobin <11 g/dL. In 70 participants with virologic failure and successful sequencing, HIVDR prevalence is 81% for any ARV, 5.7% for InSTIs, 79% for NNRTIs, and 61% for nucleos(t)ide reverse transcriptase inhibitors (NRTIs). Intermediate-to-high resistance to ≥1 NRTI in current ART is less prevalent with DTG+2NRTIs than NNRTI+2NRTIs regimens (aPR = 0.5, 95%CI 0.3-0.8).
conclusionsMost participants in the cohort are virologically-suppressed. Among those with virologic failure, HIVDR prevalence is high to NRTIs and NNRTIs, but low to InSTIs. Ongoing evaluation is necessary to determine the durability of DTG-based ART.
