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

backgroundAs Japan's aging society needs more blood, young students comprise a progressively smaller portion of the donor pool. To ensure a safe and sustainable blood supply, it is crucial to select suitable donors. This study aims to evaluate donor deferral rates, causes of deferral, and characteristics of deferred Japanese students.

methodsComputerized records of blood centers in northern Japan (Miyagi and Fukushima Prefectures) from March 2010 through March 2011 were retrospectively analyzed.

resultsAmong 231,361 individuals visiting during the 12-month period, 24,778 were students. Of these, 19,193 (77%) attempted donation, and 5,585 (23%) were deferred. Low hemoglobin, questionnaire-based interview decisions, and medication were the main reasons for temporary deferral. Age, sex, and blood center location were associated with low hemoglobin; donation history and blood center location were associated with medication-based deferral. The odds ratio among female students deferred for low hemoglobin was 35.48 with a 95% CI of 27.74-45.38.

conclusionsThese results suggest that continued efforts are needed to motivate deferred potential donors to return, to prevent low hemoglobin especially among females, and to review medical interview decisions, while paying close attention to regional differences.
