Association between ABO blood groups and their clinical indices during COVID-19 infection.
Article in Asian journal of transfusion science. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimTo explore the association of ABO blood groups with COVID-19 severity, mortality, hospital stay, and their clinical indices.
methodsRetrospective clinical data from 185 COVID-19 patients were stratified into four-time points based on their survival status and length of hospital stay (<8> days). Chi-square tests, two-way ANOVA, multinomial logistic regression analyses, and multivariate logistic regression analyses were used to study their associations, strengths, and risk.
resultsThe frequency distributions of blood groups among COVID-19 patients were A (19.45%), B (26.48%); AB (7.02%); and O (47.02%), respectively. Even though patients in the O-blood group had the highest infection rate (47.02%), patients in the AB blood group had the maximum severity and mortality and patients in the A-blood group had the most negligible mortality. The mean overall survival time among different blood groups was O (23), A (19), B (24), and AB (17) days. Mean platelet count (%), aggregate index of systemic inflammation (AISI), Platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and hospital stay were increased (
conclusionsEven though O blood group patients had the highest infection rate, AB group patients had the most severe disease accompanied by the least survival. Higher (AISI, PLR, SII, and higher TLC) were associated among the survivors of the AB blood group.
