Urinary ferritin; a potential noninvasive way to screen NICU patients for iron deficiency.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
objectiveBuilding on our previous study, showing a correlation between ferritin in serum and urine, we conducted a feasibility evaluation, measuring urinary ferritin as a potential noninvasive screening test for iron deficiency among NICU patients. STUDY
designThis was a prospective analysis of paired serum/urine ferritin levels. We defined iron-limited erythropoiesis by a RET-He <5th percentile lower reference interval (<28 pg).
resultsWe obtained 49 paired serum/urine samples from neonates judged as at-risk for iron deficiency. Urine ferritin ("corrected" for urine creatinine and specific gravity) correlated with serum ferritin (correlation coefficient of log
conclusionsMeasuring urinary ferritin in NICU patients is feasible. Since low values identify iron-limitation, this could become a useful noninvasive screen.
