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

Immunocompromised patients with prolonged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections may serve as reservoirs for viral evolution, with suboptimal immune responses facilitating the accumulation of adaptive mutations. This study aimed to characterize the drivers of SARS-CoV-2 adaptive evolution in such hosts through genomic surveillance. We retrospectively analyzed 24 patients with long-term positive nasopharyngeal reverse transcription-polymerase chain reaction results (symptom onset duration: 7-14 days on average, 1 HIV-positive patient with >20 days of infection). Most infections (April-May 2022) were caused by Omicron variants (predominantly BA.2). Phylogenetic analysis revealed accelerated viral evolution in patients with diverse underlying diseases (e.g., HIV and esophageal cancer). A total of 78 intrahost single-nucleotide variants were identified, with ORF1ab (53.8%) and the Spike protein coding region (20.5%) being hotspots. Notably, the HIV-positive patient's virus developed unique mutations: NSP3-T779I, NSP15-A94T, and Spike double mutations N440K and I794T. Functional assays showed that the N440K/I794T double mutation significantly enhanced infectivity in Hela-hACE2 cells (
