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
Objective: To evaluate the prevalence and factors associated with supplementation of ferrous sulfate and folic acid in pregnant people. Methods: A cross-sectional, representative study with pregnant people treated in Primary Health Care in Criciúma, Santa Catarina, in 2023. Ferrous sulfate and folic acid supplements were evaluated based on the prenatal booklet for pregnant people. The prevalence of supplementation was calculated with their respective 95% confidence intervals (95%CI). Crude and adjusted Poisson regression analyses (hierarchical model) were performed, estimating prevalence ratios (PR) and their respective 95%CI, to verify the associated factors. Results: A total of 428 pregnant people were interviewed. Of these, 97.4% used ferrous sulfate supplementation during pregnancy, and 93.7% folic acid. The analyses indicated that the use of ferrous sulfate was higher in older pregnant people, with PR 1.06 (95%CI 0.99; 1.13), and who consumed alcohol during pregnancy, with PR 1.04 (95%CI 1.00; 1.08). Regarding the use of folic acid, it was higher among pregnant people who had at least six prenatal visits, with PR 1.10 (95%CI 1.01; 1.20). Conclusion: The results indicate high iron and folic acid supplementation among pregnant people in Primary Health Care. The identification of associated factors can guide more targeted and effective intervention strategies by Health Management.
