Lead: a hidden "untested" risk in neonatal blood transfusion.
Article in Pediatric research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundNeonates may be exposed to lead (Pb) through blood transfusions from donors. Pb exposure has neurological, cardiovascular, renal, and other adverse effects. The study aimed to (i) determine the blood lead levels (BLLs) in different blood product units (whole blood, packed red blood cells (pRBCs), platelets, and plasma transfused to neonates) and (ii) estimate the proportion of units with high BLLs.
methodsResidual blood from blood bank bags that were used for neonatal transfusion were collected: 25 samples from each type of blood product except for whole blood (10 samples). The Pb analysis was performed using the atomic absorption method. The study was conducted at the Suez Canal University Hospital, Egypt.
resultsThe mean of BLL in pRBCs, platelets, plasma, and whole blood were 136, 199, 108, and 130 µg/L, respectively; 60% contained Pb above 50 µg/L. The highest BLLs were in platelet units.
conclusionsThe present study showed for the first time that platelets and plasma in addition to whole blood and pRBCs used for neonatal transfusions are sources of Pb. Re-evaluation of the guidelines is mandatory for the safety of the neonates. Long-term neurodevelopment assessment of neonates exposed to high Pb is warranted.
