Association of regular plasmapheresis donation with serum protein and electrolyte levels: a multicentre cross-sectional study in China.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundChina's plasmapheresis donation policy differs from that of Western countries. The association between regular plasmapheresis donation and donor health in China is still unknown.
objectivesTo investigate the association of regular plasmapheresis donation with serum protein and electrolyte levels and provide scientific evidence for policy improvement.
designMulticentre cross-sectional study. SETTING AND
participantsA total of 767 regular and 726 new donors from the provinces of Sichuan, Hunan, Henan and Yunnan were recruited from September 2021 to October 2022. PRIMARY AND SECONDARY OUTCOME MEASURES: Our primary outcome focused on measuring the levels of serum protein and electrolyte levels, including total serum protein (TSP), IgG, albumin (Alb), haemoglobin (Hb), calcium, potassium (K
resultsMale and female donors in the high donation frequency group (>16 donations per year) exhibited lower IgG levels compared with new donors (p=0.008 for male donors and p=0.007 for female donors). Additionally, female donors with high donation frequency and a high total number of lifetime donations (>100 donations) had significantly lower Hb concentrations than new donors. However, no significant changes were observed in TSP, Alb, calcium, K
conclusionsPlasmapheresis donation is not associated with an increased risk of abnormalities in the analysed parameters. However, the results provide preliminary evidence supporting the routine inclusion of IgG screening for donors, as plasmapheresis donation is associated with a decrease in IgG levels. Particular attention should be paid to the Hb levels of female donors, especially those who donate frequently. Testing of TSP at each donation may not be necessary.
