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

backgroundRegular blood donation has been associated with lower cardiovascular risk in some studies, possibly through mechanisms involving reduced iron stores and oxidative stress.

objectiveThe study investigated the association between blood donation frequency and cardiovascular risk factors among voluntary blood donors.

methodsThe cross-sectional study examined blood donors classified into regular donors and occasional donors. Blood pressure, body mass index (BMI), fasting blood glucose, and total cholesterol levels were measured. Standard clinical criteria were used to determine the cardiovascular risk factors. Independent t-tests and chi-square tests were analyzed to compare the two groups. Multivariate logistic regression was applied to control for possible confounding variables.

resultsRegular donors demonstrated lower blood pressure measurements, which included systolic blood pressure of 118 ± 12 mmHg and diastolic blood pressure of 77 ± 8 mmHg. Donors who donated regularly demonstrated a lower BMI of 24.5 ± 3.1 kg/m

conclusionRegular blood donation was associated with more favorable cardiovascular risk profiles among donors in this study.
