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

Influenza vaccination is particularly important for pregnant women. Using a test-negative, case-control design, we estimated the effectiveness of 2023-2024 seasonal influenza vaccination against influenza-associated emergency department and urgent care (ED/UC) encounters among pregnant and non-pregnant women of reproductive age using data from seven healthcare systems. Eligible encounters were among individuals aged 18-49 years with documented female sex. Vaccine effectiveness (VE) was estimated by comparing the odds of vaccination among influenza-positive cases versus influenza-negative controls, adjusting for site, age, race/ethnicity, calendar time, and gestational age at encounter (in pregnant women). Among pregnant women (N = 3539), VE against influenza-associated ED/UC encounters was 46 % (95 % CI: 36-55) and did not differ by gestational age at vaccination. Among non-pregnant women (N = 57,709), VE against influenza-associated ED/UC encounters was 54 % (95 % CI: 51-56). Influenza vaccination during the 2023-2024 season was similarly effective in both pregnant and non-pregnant women and by timing of vaccine receipt during pregnancy.
