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

backgroundThe aim of this study was to determine any relationships between return rates of first-time donors, number of donations in the first year and the donors' demographic characteristics. MATERIALS AND

methodsData from 1,500 volunteer, first-time donors who donated blood at Shiraz Blood Transfusion Centre (Iran) were obtained from the donor database. The donors' demographic characteristics (sex, age, educational status) and donation histories were obtained for a 3-year period and the number of donations and interval between the first donation and the following donation within a 1-year period were recorded. We searched for correlations between return rate and demographic characteristics and the number of donations in the first, second and third years. The data were analysed with the chi-squared test, multiple logistic regression and Spearman's correlation tests. P values less than 0.05 were considered statistically significant.

resultsMore than half of the first-time donors returned to donate again (n=776, 51.7%) during the 3 years after the first donation. The mean number of donations in the whole 3-year period was 0.69±0.49, while it was 1.33±0.62 (median 1) in the first year, 0.4±0.7 (median 0) in the second, and 0.3±0.65 (median 0) in the third year. The return rate was directly correlated with the number of donations in the first year (r=0.74, P<0.001). The return rate increased as the interval between the first and second donations decreased (P<0.05, OR=1.03). The return rate was higher for male donors and single donors (P<0.05), but was not related to age or educational level (P>0.05). DISCUSSION: In this study 51.7% of first-time donors returned to donate again, a high figure indicating the success of our recruitment strategy. Understanding the importance of the number of donations in the first year for donors' return rate and planning recruitment programs and more effective measures to encourage donors in the first year may help to increase return rates.
