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
backgroundFollowing the emergence of COVID-19 disease, and considering the limited number of studies regarding vaccination among pregnant women, as well as the differences between the vaccine administered in Iran and those used in other countries, this study aimed to compare maternal and neonatal outcomes in vaccinated and unvaccinated women against COVID-19 disease.
methodsThis retrospective cohort study was conducted at the comprehensive healthcare centers of Rafsanjan city. Initially, the contact information of expectant mothers who were pregnant between June 22, 2021, and December 22, 2021, was obtained through Iran's integrated healthcare system (Sib). Subsequently, the required information was collected via a checklist during phone interviews. Out of 969 pregnant women, after applying the inclusion and exclusion criteria, 610 subjects were included in the study. Among these, 330 were unvaccinated, while the remaining participants had received the inactivated COVID-19 vaccine prior to or during pregnancy. Maternal and neonatal outcomes were compared between vaccinated and unvaccinated women. Data analysis was performed using SPSS version 26, employing one-way analysis of variance (ANOVA), Tukey's multiple comparison test, Fisher's exact test, Chi-square test, and multiple logistic regression.
resultsThe findings indicated that vaccination against COVID-19 in pregnant women significantly increased the risk of neonatal jaundice (P < 0.05). Conversely, the miscarriage rate among these women was significantly lower (P < 0.05). No adverse outcomes were observed including hypertensive disorders, gestational diabetes, maternal hospitalization, maternal COVID-19 infection, preterm labor, premature rupture of membranes, perinatal mortality, admission to the neonatal intensive care unit, and low birth weight.
conclusionsCOVID-19 Vaccination is recommended for pregnant women to mitigate adverse neonatal and maternal outcomes.
