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 describe the prevalence of perinatal death in Tongzhou District of Beijing, and to estimate the association between maternal periconceptional supplementation of folic acid or multiple micronutrients containing folic acid and perinatal mortality rate.
methodsA retrospective cohort study was conducted based on the maternal and child care system in Tongzhou District of Beijing. The subjects were 94 490 perinatal who were born during January 2013 to December 2018. The information on perinatal outcomes and maternal periconceptional supplementation of folic acid or multiple micronutrients containing folic acid were collected. The Poisson log-linear model was used to estimate the association between maternal periconceptional folic acid or multiple micronutrients supplementation and perinatal mortality rate.
resultsThe overall perinatal mortality rate was 2.71‰. The perinatal mortality rates for maternal nutrients supplementation containing folic acid and no supplementation during periconceptional period were 2.63‰ and 3.43‰, respectively, and the difference in rates was not statistically significant [crude risk ratio (
conclusionThe overall perinatal mortality rate was lower than the national average level in Tongzhou District of Beijing. Maternal periconceptional supplementation of pure folic acid or micronutrients containing folic acid had no impact on perinatal mortality. The association between maternal periconceptional supplementation of multiple micronutrients containing folic acid and perinatal mortality rate need further research.
