Is Routine Iron Supplementation Necessary in Pregnant Women With High Hemoglobin?

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
backgroundIron supplementation is a chief component in prenatal care, with the aim of preventing anemia; however, extreme maternal iron status may adversely affect the birth outcome. Given the negative consequences of high maternal iron concentrations on pregnancy outcomes, it seems that iron supplementation in women with high hemoglobin (Hb) should be limited.
objectivesThe aim of this study was to examine the effect of iron supplementation on iron status markers in pregnant women with high Hb. PATIENTS AND
methodsIn a randomized, double-blind, placebo-controlled trial, 86 pregnant women with Hb > 13.2 g/dL and ferritin > 15 μg/l in the 16th - 20th week of pregnancy were randomized into experimental and control groups. From the 20th week until the end of pregnancy, the experimental group received one ferrous sulfate tablet containing 50 mg of elemental iron daily, while the control group received a placebo. Hb and ferritin levels at 37 - 39 weeks of pregnancy were evaluated and compared. In addition, after delivery the birth weight was measured in two groups and compared.
resultsThere were statistically significant differences between the two groups in Hb (p = 0/03) and ferritin (p = 0/04) levels at the end of pregnancy, but the incidence of anemia exhibited no difference in either group (p < 0/001). In addition, the mean of birth weight in experimental group and control group were 3391/56 ± 422, 3314/06 ± 341, respectively and it was not significant difference (p = 0.2).
conclusionsNot using iron supplementation did not cause of anemia in women with Hb concentrations greater than 13.2 g/dL during pregnancy; thus, the systematic care and control of iron status markers without iron supplementation is recommended for these women.
