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

backgroundBlood donors receiving testosterone replacement therapy (TRT) often require therapeutic phlebotomy due to erythrocytosis. Red blood cells (RBCs) donated by eligible TRT donors are approved for collection and transfusion. This study was aimed at defining the prevalence and demographic determinants of TRT donors at a large USA blood service organization. STUDY

designDonation data from TRT donors and matched controls was collected from a de-identified electronic donor database across 16 blood centers in 2017-2018. Demographic determinants included race, sex, age, hemoglobin (Hb), body mass index (BMI), mean arterial pressure (MAP), and the frequency of donations in the 2-year period.

resultsTRT donors comprised 1.6% of the donor population and produced 2.2% of RBC units during 2018. TRT donors were likely to be middle-aged white or Hispanic men, with high prevalence of obesity (50.8% of TRT donors had BMI ≥30 kg/m

conclusionsTRT is associated with high prevalence of erythrocytosis and obesity that may explain the intensive donation frequency, high MAP, and Hb. Frequent phlebotomies had a moderately positive effect on blood pressure and Hb levels. Potential implications of TRT on the quality of the RBC products require further evaluation.
