Genotyping not required for sustained effectiveness of long-acting cabotegravir plus rilpivirine: evidence from the RELATIVITY cohort.
Article in AIDS (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesLong-acting injectable cabotegravir and rilpivirine (LAI CAB+RPV) provides an alternative to daily therapy for people with HIV (PWH) with virologic suppression. Although genotypic testing is recommended before switching, its real-world clinical value is unclear. We assessed outcomes after switching to LAI CAB+RPV with or without available genotypes in the Spanish RELATIVITY cohort.
designRELATIVITY is a multicenter, ambispective cohort study assessing the effectiveness and safety of LAI CAB+RPV in adults with HIV across 58 centers in Spain.
methodsPosthoc analysis of 3146 participants, focusing on the availability of genotypic resistance data before switching.
resultsOf the 3146 participants, 53.5% ( n = 1682) did not have genotypes available. The median follow-up was 13.3 months [interquartile range (IQR) 8.6, 18.9] in the no-genotype group and 14.9 months (IQR 9.0, 19.2) in the genotype group ( P = 0.003). Both groups maintained high virological suppression rates (>93%) up to the 23rd month of follow-up, with no significant differences observed in virological or immunological outcomes. Virologic failure rates (0.5% vs. 1.0%; P = 0.476) and permanent discontinuation rates (6.1% vs. 6.6%; P = 0.804) were similar. Of the 20 participants with virologic failure, 12 had genotype data. After resuming oral antiretroviral therapy, 8 of those with and 4 of those without the genotype achieved undetectable viral loads. Adherence to injection schedules and changes in body mass index were comparable.
conclusionsIn this large real-world cohort, the absence of genotypic data did not affect LAI CAB+RPV effectiveness in virologically suppressed PWH. Limitations, including ambispective design, short follow-up, and low non-B subtype prevalence, may limit generalizability.
