Maternal haemoglobin concentrations before and during pregnancy as determinants of the concentrations of children at 3-5 years of age: A large follow-up study.
Article in European journal of clinical nutrition, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveTo examine the association between haemoglobin (Hb) concentrations in mothers before and during pregnancy and those in children at 3-5 years of age.
methodsThe study included 78,923 women who conceived during 1993-1996 and delivered a singleton live infant. Maternal Hb concentrations were measured at pre-pregnancy health check-up and first prenatal visit, and during the second and third trimester. Hb concentrations of children born to these women were measured at 3-5 years of age. Associations between Hb levels in mothers and children were examined. Unconditional logistic regression was used to explore the association between maternal Hb levels and risk for anaemia in children.
resultsMaternal Hb levels before and during pregnancy were positively associated with children's Hb levels. Using maternal Hb ≥ 130 g/L as the referent, the risk for anaemia in children at 3-5 years of age was higher when maternal second trimester Hb concentrations were 70-99 g/L (odds ratio [OR] = 1.76, 95% confidence interval [CI] = 1.56-1.99), 100-109 g/L (OR = 1.45, 95% CI = 1.29-1.64), and 110-119 g/L (OR = 1.18, 95% CI = 1.04-1.33). Children were 1.52 and 1.23-times more likely to suffer from anaemia when maternal third trimester Hb concentrations were 70-99 and 100-109 g/L, respectively. A pre-pregnancy Hb concentration of 80-109 g/L and first prenatal visit Hb concentrations of 80-109 and 100-119 g/L were also associated with increased risks for childhood anaemia.
conclusionLow maternal Hb concentrations before or during pregnancy increase the risk for anaemia in children at 3-5 years of age.
