Evaluation of the distribution of ABO and Rh blood groups in geriatric patients aged ≥85 years: A retrospective single-center study.

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
The study aimed to determine whether significant differences exist in blood group type distribution between the elderly population and a younger population. The geriatric group consisted of 2247 patients aged 85 years and older. As for the control group, 2968 individuals aged 20 to 22 years were included. The primary objective was to assess the distribution of ABO and Rh blood group types within each study group and to identify any statistically significant differences between the geriatric and control groups. Analysis considering both ABO and Rh blood types indicated that A Rh(+) was the most common type in both groups. Conversely, AB Rh(-) was the rarest type in both groups. Additionally, statistical analysis revealed no significant difference in ABO blood group type frequencies between the 2 groups (P = .121). Furthermore, there was no statistically significant difference between the groups in terms of the frequency of Rh positivity: 88.7% in the geriatric patient group and 88.4% in the control group (P = .748). Our findings suggest that ABO/Rh blood type diversity may not be a significant determinant of longevity in individuals aged 85 years and above.
