No Association Between HIV-1 Subtype and Primary Resistance Mutations with CD4 Reconstitution During Effective Antiretroviral Treatment: An Observational, Cohort Study.
Observational study in International journal of molecular sciences, 2025. 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
Some people with Human Immunodeficiency Virus (HIV) on effective antiretroviral therapy have persistent low lymphocyte CD4 counts and remain at an increased risk of Acquired Immunodeficiency Syndrome (AIDS). We investigated whether primary drug resistance mutations (DRMs) and HIV-1 subtype could be related to immunologic reconstitution in these people. In a multicenter, observational cohort study among treatment-naïve patients, we analyzed HIV-1 subtype, primary drug resistance mutations, CD4 counts, and CD4:CD8 ratios during effective antiretroviral therapy. We compared these variables between patients with different HIV subtypes and between those with or without drug-resistance mutations up to 48 weeks post-baseline. In 156 patients, CD4 count normalization (≥500 cells/µL) was observed in 39% of patients, while CD4:CD8 ratio ≥ 1 in 27% after treatment implementation. HIV-1 subtype B was present in 75% of the patients and subtype A in 22%. Primary resistance mutations were found in 57% of the individuals. The percentage of immunological nonrespondents did not differ significantly between those with different HIV subtypes or between those with or without primary resistance mutations (
