Results of Pregnancy Control before and during the COVID-19 Pandemic: A Comparison of Two Cohorts.
Article in International journal of environmental research and public health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
The COVID-19 pandemic placed pregnant women at high risk, but behavioural changes have also led to lower rates of preterm births in high-income countries. The main goal of this article is to study the ongoing impact of the COVID-19 pandemic on pregnancy control and outcomes; this is a joint analysis of two cohorts. The pre-pandemic cohort includes 969 pregnant women recruited in 2018. The pandemic cohort comprises 1168 pregnant women recruited in 2020. Information on demographic and socioeconomic characteristics, reproductive history, characteristics of the current pregnancy and its outcome were obtained from medical records. Birth by Caesarean section was more frequent in the pre-pandemic cohort (adjusted odds ratio (OR) = 0.71, 95% confidence interval (CI): 0.55-0.92). A birth weight lower than 2500 g and higher than 4000 g occurred more frequently in the pre-pandemic cohort (adjusted OR = 0.62, 95% CI: 0.41-0.93 for lower than 2500 g and adjusted OR = 0.30, 95% CI: 0.20-0.46 for higher than 4000 g). Exclusive breastfeeding upon hospital discharge was more frequent in the pandemic cohort than in the pre-pandemic cohort (60% vs. 54%,
