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
backgroundHIV drug resistance can reduce the effectiveness of antiretroviral drugs in preventing morbidity and mortality, limit options for treatment, and prevention. Our study aimed to assess HIV-1 subtypes and HIV drug resistance among key populations in HIV Sentinel Surveillance Plus Behavior in 2018 and 2020.
methodsOne-stage venue-based cluster sampling was used to recruit participants at hotspots identified for men who have sex with men (MSM) in 7 provinces and sexual minority females and female sex workers (FSW) in 13 provinces. Participants completed a standard questionnaire about risk and preventive behaviors, and antiretroviral therapy history, and provided intravenous blood for HIV testing. HIV drug resistance testing was conducted on HIV-positive samples with viral load >1000 copies/mL.
resultsA total of 185 of 435 (42.5%) HIV-positive samples had viral load ≥1000 copies/mL, of which 130 of 136 from MSM and 26 of 49 from FSW were successfully sequenced. Six HIV-1 subtypes were detected (CRF01_AE, A, CRF07/08_BC, B, C, CRF25_cpx), with CRF01_AE (82.7%, 129/156) the most common. Drug resistance mutations were detected in 16.7% of participants overall (26/156), in 15.4% (20/130) of MSM, and in 23.1% (6/26) of FSW. Mutations associated with resistance to non-nucleoside reverse transcriptase inhibitor (NNRTI) were the most frequently detected (73.1%, 19/26). The high level of resistance was presented in NNRTI and nucleoside reverse transcriptase inhibitors classes. There are 10 major resistance mutations detected with nucleoside reverse transcriptase inhibitors (M184VI-25.0%, K65KR-50.0%, Y115F-25%), NNRTI (K103N-21.1%, E138A-10.5%, V106M-5.3%, K101E-5.3%, G190A-5.3%), protease inhibitors (L33F-40.0%, M46L-20.0%).
conclusionsVietnam's HIV Sentinel Surveillance Plus system identified an emerging strain of HIV-1 and mutations associated with resistance to multiple drug classes among MSM and FSW.
