Genetic diversity and antiretroviral resistance of human immunodeficiency virus type 1 in Peruvian military personnel during one year of follow-up
Article in Biomedica : revista del Instituto Nacional de Salud, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction. The factors affecting genetic diversity and antiretroviral therapy resistance mutations in human immunodeficiency virus (HIV) type 1 in military personnel are unknown. Objective. To describe the factors affecting genetic variability and resistance to HIV antiretrovirals in the military population during one year of follow-up. Materials and methods. Fifty-two Peruvian military personnel living with HIV and receiving antiretroviral therapy were recruited. Genetic diversity, genetic subtypes, recombination events, and resistance profile occurring in protease and reverse transcriptase genes were compared at 12 and 18 month follow-up, taking into account the socio-epidemiological characteristics of the participants. Results. Intermittent condom use (37%), contact with sex workers (17%) and a history of sexually transmitted infections (56%) were observed. The genetic diversity index (π) increased from 0.30 to 0.45, while genetic subtypes and recombinant forms did not change significantly. Of eleven samples with significant nucleotide changes, five showed resistance mutations. Finally, bivariate analysis showed that increasing subject age was significantly associated with a difference in resistance profile after an interval of 12 months or more. Conclusions. We show that, after at 12 and 18 month of follow-up, HIV-infecting a population of Peruvian military subjects underwent changes in its genetic diversity and resistance profile, which were associated with the chronological age of the participants.
