Sero-Epidemiologic Study of Respiratory Syncytial Virus Infection in Korea.
Article in Journal of Korean medical science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDespite the recent introduction of a respiratory syncytial virus (RSV) vaccine, there is no sero-epidemiologic study of RSV infection among old adults in Korea. This study aimed to assess humoral immune responses to RSV among different age groups in Korea.
methodsA total of 400 serum samples (100 samples from each of the following age groups: 10-20, 21-40, 41-60, and 61-80 years) were selected randomly from a general population cohort used for health status evaluation in Korea (the Korea National Health and Nutrition Examination Survey 2019-2020 cohort). Anti-RSV IgM and IgG levels, along with total IgM and IgG levels, were measured in enzyme-linked immunosorbent assays.
resultsAnti-RSV IgM levels were higher in individuals aged 10-20 and 21-40 years than in the other age groups (121.43 U/mL vs. 102.33 U/mL vs. 76.71 U/mL vs. 64.89 U/mL,
conclusionRSV infections are recurrent in people over the age of 40 in Korea, but at a lower rate than in those aged 10-40. Therefore, more attention should be paid to RSV infections in the adult population in Korea.
