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

Respiratory syncytial virus (RSV) vaccination is recommended in pregnancy. Limited data exist regarding antibody (Ab) durability to inform revaccination timing. We conducted prospective cohort studies among pregnant and older adults after first RSV vaccination in 2023-2024. Longitudinal samples from 50 pregnant (36 vaccinated) and 16 vaccinated older adults were collected until 12-15 months after vaccination and tested for RSV binding and neutralizing Ab. Mean Ab levels 12-15 months after vaccination were similar between vaccinated maternal and older adult participants (P = .73), suggesting Ab durability up to 1 year after maternal RSV vaccination. RSV binding and neutralizing Ab titers were strongly correlated (R = .73).
