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

SARS-CoV-2 infection during pregnancy can adversely affect maternal and neonatal health, although risks vary depending on the variant of concern (VOC). Omicron, although highly infectious, causes fewer maternal and neonatal complications than earlier VOC, so vaccination may be considered unnecessary in planned pregnancy. Using data from the CRONOS registry, we compared pregnancy outcomes according to VOC and vaccination status. We found that vaccination during pregnancy reduced preterm birth rates compared with unvaccinated or vaccinated women with Omicron infection, without increasing severe neonatal outcomes. Given the risks associated with preterm birth, the study consistently supports vaccination recommendations for women planning pregnancy.
