Prioritizing long COVID related single nucleotide polymorphisms by mining genome-wide association studies of COVID-19 susceptibility and hospitalization.

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
Long coronavirus disease (COVID) presents a significant public health challenge, characterized by over 200 reported symptoms across multiple organ systems. Genetic studies of long COVID have been hindered by the disorder's symptom heterogeneity and the limited sample size of available datasets. To overcome these challenges, a proxy-based, hypothesis-generating strategy was conducted to prioritize candidate risk loci on studying long COVID by analyzing GWAS summary statistics of coronavirus disease 2019 (COVID-19) susceptibility, hospitalization, and long COVID from the COVID-19 Host Genetics Initiative (Release 7), resulting in 62 candidate loci represented by independent variants. These variants are grouped into three categories: (1) severe COVID-19-specific variants, exhibiting reduced signals in non-hospitalized cases; (2) variants associated with both severe and mild COVID-19, and (3) non-hospitalization-specific variants associated with mild cases. Evaluation using recently published long COVID datasets from the same consortium demonstrated that most candidate variants displayed weaker associations around nominal significance, with only a single genome-wide significant signal at rs12660421 of
