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
objectivesto correlate folic acid levels with hemoglobin levels in pregnant women.
methodsa cross-sectional study conducted between 2017 and 2019 with 950 pregnant women based on the cohort database "Nutrition and Infection: The Problem Revisited Due to the Microcephaly Outbreak". Data were analyzed using Stata 12.1. Spearman's correlation and Pearson's chi-square tests were applied, with a significance level of 5%.
resultsfolic acid and hemoglobin levels were adequate (>5.38 ng/ml) in 90.9% of participants. Hemoglobin concentration was adequate (≥ 11 g/dL) in 80.8% of pregnant women. Pregnant women with hemoglobin ≤ 11 g/dL had 13.2% of inadequate folic acid, while in the group with hemoglobin ≥ 11 g/dL, 8.1% had inadequate folic acid (p=0.031).
conclusionsan association was observed between hemoglobin and folic acid levels in the pregnant women assessed, reinforcing the importance of nutritional monitoring during prenatal care.
