Iron supplementation for preterm infants receiving restrictive red blood cell transfusions: reassessment of practice safety.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2010. 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
objectiveTo reassess iron supplementation practice safety in very low birth weight (VLBW) preterm infants receiving restrictive red blood cell transfusions during initial hospitalization. STUDY
designIron status, including hemoglobin (Hb), serum iron, ferritin, and soluble transferrin receptor (sTfR) levels and reticulocyte count of transfused (n=236) and non-transfused (n=166) preterm infants at ≤24 h and 2, 4 and 8 weeks were recorded. As per protocol, a restrictive blood transfusion policy and supplementation of 5 mg kg(-1) per day of iron polymaltose complex from 4 weeks and 25 mg(-1) per day of vitamin E from 2 weeks were imposed for all infants. Normative reference cord-blood ferritin value of preterm infants was used for comparison. Vitamin E levels and incidence of morbidities associated with prematurity were recorded.
resultAt ≤24 h, the characteristics and iron status of both groups were similar. At 2, 4 and 8 weeks, the transfused group had significantly higher Hb, iron and ferritin levels; sTfR levels were lower at 4 and 8 weeks (all indices, P<0.05). At 8 weeks, the median ferritin levels of our transfused group were lower than that of normative reference cord-blood value (115 (50th percentile) vs 79 (43 to 107) μg l(-1), respectively). Vitamin E levels and the incidence of morbidities associated with prematurity of the transfused and non-transfused groups were not different (both indices, P>0.18).
conclusionAdding iron supplementation to preterm infants receiving restrictive blood transfusions has shown to be a judicious and safe practice in terms of iron status for VLBW preterm infants.
