Association between maternal anemia and cord blood hemoglobin and ferritin concentrations in newborns: a Single-center study in Turkey.

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
backgroundThe purpose of this study was to evaluate the effect of third-trimester maternal iron deficiency and iron deficiency anemia on neonatal cord-blood hemoglobin (Hgb), and serum ferritin levels.
methodsPregnant women who gave birth between 37
resultsAmong 627 women included, 226(36%) were diagnosed as anemic, of which 130(57.5%) had mild, 94(41.6%) moderate, and 2(0.9%) severe anemia. Mean maternal Hb levels were 9.9±0.9 g/dl and 12.1±0.9 g/dl in the anemic and non-anemic groups, respectively. The mean maternal serum ferritin of anemic and non-anemic mothers were 11.7 ng/ml and 15.8 ng/ml, respectively (p < 0.001). The mean cord-blood serum ferritin of neonates born from anemic and non-anemic mothers was 113±68.8 ng/ml and 134±95.0 ng/ml, respectively (p = 0.012). Cord-blood Hb levels of neonates born from anemic and non-anemic mothers were 15.1±1.8 g/dl and 15.5±2.0 g/dl, respectively (p = 0.006). The 5th, 25th, 50th, 75th, and 95th percentiles of cord blood serum ferritin concentrations were 32.6, 72.2, 107.5, 154.1, and 272.6 ng/ml, respectively. Among neonates born from mild, moderate, and severe anemic mothers, there was no significant difference regarding cord-blood serum ferritin and blood count parameters (p > 0.05). Cord-blood serum ferritin concentrations were found to be 119 ± 85.7 ng/ml and 136.4 ± 87.9 ng/ml in the low and normal maternal serum ferritin groups, respectively (p = 0.015).
conclusionMaternal anemia is common and associated with lower neonatal cord blood hemoglobin and ferritin levels. However, lack of iron supplementation during pregnancy, rather than anemia itself, was the strongest independent predictor of neonatal anemia. These findings highlight the importance of routine antenatal iron supplementation to support fetal iron status and improve perinatal outcomes. Further randomized controlled trials are needed to evaluate the effects of maternal iron supplementation on fetal iron stores and long-term outcomes.
