Association between gestational anemia in different trimesters and neonatal outcomes: a retrospective longitudinal cohort study.
Article in World journal of pediatrics : WJP, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 4 of them syntheses that pooled it.
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
backgroundPrevious studies investigated the association between gestational anemia and neonatal outcomes. However, few studies explored whether the effects of gestational anemia could be eliminated by subsequent correction of anemia in the later stages of pregnancy. This study aimed to investigate the relationship between anemia in different trimesters and neonatal outcomes.
methodsThe study was conducted in Shanghai, China, with a sample of 46,578 pregnant women who delivered between January 1, 2016 and July 1, 2019. A multivariable logistic regression model was adopted to analyse the associations between maternal anemia and neonatal outcomes.
resultsThe incidence of gestational anemia was 30.2%, including 4.4% in the first trimester, 9.6% in the second trimester, and 16.2% in the third trimester. Only 24.5% (507/2066) of anemia that occurred in the first trimester and 29.6% (1320/4457) that occurred in the second trimester could be corrected in the later stages of pregnancy. Anemia occurring in the first trimester was associated with small for gestational age [odds ratio (OR) 1.46; 95% confidence interval (CI) 1.20-1.78] and with fetal distress (OR 1.23; 95% CI 1.08-1.40). Anemia corrected in the first trimester also was associated with a higher risk of small for gestational age.
conclusionsGestational anemia is a public health problem in China impacting neonatal health. Anemia in pregnancy could be corrected in only about a quarter of the women. Anemia in the first trimester, whether corrected or not, still led to lower birth weight; therefore, the prevention of anemia prior to pregnancy is important.
