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

introductionThe safety of a blood transfusion practice is anchored on safe blood from a healthy donor, while further protecting the donor from future harm. This study aimed to evaluate the hematological parameters of blood donors in view of their donor category to aid in assessing the safety threshold in terms of donation frequency.

methodsThis study made use of the descriptive cross-sectional design. The blood donors were bled and their samples analyzed using a hematology autoanalyzer.

resultsA total of 178 male blood donors were recruited. Most of the donors were aged 18 to 39 years and were mostly students. A greater part of them were repeat donors who had donated blood more than four times. First- and second-time donors constituted the majority of the voluntary donors. While the total red cell count was significantly lower in repeat third-time donors, the hemoglobin and hematocrit of the first-time donors were significantly higher than those of the repeat fourth-time donors. The mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) of the first-time donors were significantly higher than those of the repeat fifth-time donors. The red cell distribution width (RDW) and mean platelet volume (MPV) were significantly lower in the first-time donors from those of the sixth- and seventh-time donors, respectively. Most of the fifth-time donors have subclinical anemia. There was more subclinical anemia in commercial donors than in voluntary donors.

conclusionRepeat donors more than fifth-time donors are at risk of donation-induced iron deficiency anemia.
