Blood Group Type and COVID-19 Severity at Tertiary Care Centre, Nepal: An Observational Study.
Observational study in JNMA; journal of the Nepal Medical Association, 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
Introduction: The respiratory infection with COVID-19 caused by the novel coronavirus SARS-CoV-2, emerged in December 2019 and was later declared a global pandemic by the world health organization. Clinical observations suggest the role of ABO blood types in susceptibility to COVID-19 infection. The study was designed to find the proportion of blood group distribution across the severity of COVID-19 patients. Methods: This is an observational cross-section study conducted at a tertiary care hospital. All COVID-19 patient visiting hospital within January to December 2021 were included in the study. Their demographic profile, blood group and COVID-19 severity were recorded. Descriptive analysis of the date was done. Results: There were 399 confirmed case of COVID-19 during study period, out of which 278 (69.7%) were male and 198 (49.62%) were aged between 21-40 years. There were 78 (31.45%) amongst mild COVID-19 and 32 (39.04%) amongst severe COVID-19 (Bilateral Pneumonia) having A positive blood group. Conclusions: The study suggests that patients with blood group A positive were more in the mild COVID-19, severe COVID-19 group.
