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.

Abstract

BACKGROUND AND

objectivesGranulocyte transfusion supports patients with severe neutropenia. Maintaining a pool of eligible donors and optimizing donation frequency are essential for ensuring an adequate supply while safeguarding donor well-being. This study investigates the impact of donation frequency on erythrogram parameters, focusing on sex-specific differences. STUDY DESIGN AND

methodsWe conducted a retrospective analysis of 343 successive granulocyte collections from 65 apheresis donors over 11 years (2012-2023). Donors were categorized by sex, and erythrogram parameters were analysed in relation to donation frequency and intervals.

resultsFrequent donations within a short inter-donation interval (≥3 in 14 days) affected subsequent pre-donation haemoglobin levels. Each additional donation within 14 days led to a decrease of 0.81 g/dL in haemoglobin (p = 0.017). A significant interaction between sex and donations within 14 days (β = 0.76, p = 0.018) indicated that frequent donations had a more pronounced negative effect on haemoglobin levels in female donors. The proportion of donations meeting the pre-donation haemoglobin eligibility criteria declined with each successive donation within 14 days (100% at first, 85.8% at second, 25% at third). Female donors showed a significant haemoglobin reduction over three donations within 14 days (13.4-11.6 g/dL, p = 0.005) compared to males (14.4 -14 g/dL, p = 0.95).

conclusionShort inter-donation intervals have a more pronounced negative effect on pre-donation haemoglobin levels in female donors, underscoring the need for individualized donation guidelines to ensure donor safety.
