Bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in treatment-naïve and treatment-experienced people with HIV: 12-month virologic effectiveness and safety outcomes in the BICSTaR Japan cohort.
Observational study in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BICSTaR (BICtegravir Single Tablet Regimen) is an ongoing, observational cohort study assessing the virologic effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in treatment-experienced (TE) and treatment-naïve (TN) people with HIV across 14 countries over 24 months. We present 12-month outcomes from participants in the BICSTaR Japan cohort. Retrospective and prospective data were pooled from people with HIV aged ≥20 years receiving B/F/TAF within routine clinical care in Japan. Outcomes included virologic effectiveness (primary endpoint; HIV-1 RNA <50 copies/mL), CD4 count, CD4/CD8 ratio, drug-related adverse events (DRAEs), persistence, and patient-reported outcomes (prospective TN cohort only). Overall, 200 participants were enrolled and included in the 12-month analysis population (150 retrospective, 50 prospective; 116 TN and 84 TE). Most participants were male at birth (99%); median age was 34 years in TN and 45 years in TE participants. At 12 months, virologic effectiveness was high: 92% (90/98) of TN and 95% (72/76) of TE participants had HIV-1 RNA <50 copies/mL (missing = excluded analysis). Median (quartile [Q]1, Q3) CD4 cell count increased by +202.0 (126.0, 311.0) cells/μL in TN (p<0.001) and +11.0 (-60.0, 87.0) cells/μL in TE (p = 0.380) participants. Through 12 months, DRAEs were reported by 13% (25/200) of all participants (16% [18/116] TN, 8% [7/84] TE); diarrhea, weight gain, and headache were the most common. Most DRAEs were mild in severity and no severe DRAEs were reported. One TN participant (<1%; 1/116) and two TE participants (2%; 2/84) discontinued B/F/TAF due to DRAEs (macrocytic anemia, vertigo, diarrhea, and headache). Treatment persistence at 12 months exceeded 98% in both TN and TE participants. In prospective TN participants, improvements in bothersome symptom count and quality-of-life measures were observed. B/F/TAF demonstrated high levels of virologic effectiveness and tolerability in people with HIV treated as part of routine clinical care in Japan.
