1 · What the graph read from 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.

2 · The registry

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

aimTo explore the impact of the Omicron variant on maternal and neonatal outcomes.

designCross-sectional cohort study of women giving live birth in a single hospital in Shanghai in December 2022.

methodsDemographic characteristics, maternal and neonatal outcomes and laboratory testing results were retrieved from medical records. Propensity score matching was used to match COVID-19-positive and -negative women. Differential analysis was used to assess associations between COVID-19 and in-hospital maternal and neonatal outcomes.

resultsA total of 1508 women were included, comprising 729 natural births, 741 caesarean sections and 38 forceps deliveries. After 1:1 matching, 310 clients were included for analysis with each 155 in COVID-19-positive and -negative groups. Higher maternal fever was found in all modes of delivery, and higher preterm birth and lower pH value of blood gas of the umbilical artery in the vaginal delivery subgroup (p < 0.05). Other maternal and neonatal outcomes showed no significant difference between COVID-19-positive and -negative clients.
