Maternal safety outcomes of respiratory syncytial vaccination during pregnancy with a large-scale database.
Article in NPJ vaccines, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This retrospective cohort study evaluated the risk of maternal safety outcomes, including preterm birth, following prefusion F protein (RSVpreF) during pregnancy compared with an unvaccinated cohort using large-scale real-world data. Propensity score matching was performed to compare the risks of preterm delivery, hypertensive disorder of pregnancy (HDP), gestational diabetes (GDM), oligohydramnios, placental abruption, intrauterine growth restriction (IUGR), and intrauterine fetal death (IUFD) to calculate the odds ratio (OR). Following the propensity score matching, 11,265 and 11,265 pregnant women with and without RSVpreF vaccination were included, respectively. After matching, the ORs in the vaccinated group compared with the unvaccinated group were 0.98 [0.84-1.14], p = 0.789; 1.01 [0.96-1.08], p = 0.644; 0.98 [0.90-1.06], p = 0.570; 0.77 [0.63-0.95], p = 0.015; 0.99 [0.77-1.27], p = 0.949; 0.94 [0.86-1.03], p = 0.189; and 0.68 [0.38-1.22], p = 0.189 for pre-term delivery, HDP, GDM, oligohydramnios, placental abruption, IUGR, and IUFD, respectively. Maternal RSV vaccination did not increase the risk of selected maternal outcome events. However, further safety monitoring with larger sample size is required to detect rare events or small risk differences.
