Real-world effectiveness and safety of switching to dolutegravir/lamivudine among people living with HIV-1 aged over 50 years who are virologically suppressed.
Observational study in HIV 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
objectivesPeople living with HIV face several challenges as they age, including the potential for polypharmacy and increased susceptibility to drug-related adverse effects. Thus, effective and well-tolerated regimens with minimal or no drug interactions would be useful in this population. We present real-world effectiveness and safety data for individuals aged >50 years who achieved virological suppression (HIV-1 RNA <50 copies/mL) and switched to dolutegravir/lamivudine (DTG/3TC).
methodsThis retrospective, observational, single-centre study conducted in Portugal included individuals aged >50 years who switched to DTG/3TC while virologically suppressed and had ≥12 months of follow-up. Proportions of individuals maintaining virological suppression were described at 12 months; CD4+ cell counts were described at baseline and 12 months. Descriptive subgroup analyses were performed based on age, sex assigned at birth, and availability of historical genotypic resistance results.
resultsOverall, 538 individuals aged >50 years were included (74% male; mean age, 62 years; mean time on previous therapy, 160 months). High proportions (intention-to-treat population, 97%; on-treatment population, 98%) of individuals who switched to DTG/3TC maintained virological suppression through 12 months of follow-up. CD4+ cell counts remained stable (mean baseline: 727 cells/mm
conclusionsDTG/3TC demonstrated robust effectiveness and a good safety profile in individuals aged >50 years with virological suppression in Portugal.
