1 · What the graph read from it

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.

2 · The registry

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

Characterizing the HIV-1 reservoir in blood and tissues is crucial for the development of curative strategies. Using an HIV Tat mRNA-containing lipid nanoparticle (Tat-LNP) in combination with panobinostat, we show that p24+ cells from blood and lymph nodes exhibit distinct phenotypes. Blood p24+ cells are found in both central/transitional (TCM/TTM) and effector memory subsets, mostly lack CXCR5 expression and are enriched in GZMA+ cells. In contrast, most lymph node p24+ cells display a TCM/TTM phenotype, with approximately 50% expressing CXCR5 and nearly all lacking GZMA expression. Furthermore, germinal center T follicular helper cells do not appear to harbor the translation-competent reservoir in long-term suppressed individuals. Near full-length HIV-1 sequencing in longitudinal samples from matched blood, lymph nodes, and gut indicates that clones of infected cells, including those carrying an inducible provirus, persist and spread across various anatomical compartments. Finally, uniform genetic diversity across sites suggests the absence of ongoing replication in tissues under treatment.
