Measles Outbreak Investigation at a University Dormitory in the Republic of Korea, 2024.

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
backgroundFive international students from Uzbekistan were diagnosed with measles in a university dormitory on April 15, 2024. This study was an epidemiological investigation to identify the transmission route of the measles outbreak in University A and to prevent further spread.
methodsMeasles cases were defined as individuals who tested positive for measles virus using real-time reverse transcription polymerase chain reaction. A retrospective cohort study was conducted on the dormitory residents. Relative risks and 95% confidence intervals were calculated to assess risk factors in the dormitory. Measles antibody testing was performed to assess immunity. Measles vaccinations and cohort isolation were implemented in the dormitory residents to control the outbreak.
resultsThe primary case, also the index case, was a 19-year-old male student from Uzbekistan who resided on the second floor of the dormitory. All cases were reported among dormitory residents, with an attack rate of 5.3% (22/418). The student's mother in Uzbekistan had contracted measles. Risk factors for measles transmission included men, teenagers, students in the Global Business Department, students from Uzbekistan, and those who resided on the second and third floors of the dormitory. The seropositivity rate of anti-measles immunoglobulin G in Uzbek residents was 26.5%, which was lower than those in Vietnamese (36.8%) and Kyrgyzstani (41.7%) residents. No additional infections were reported after the last two cases on April 19.
conclusionThe measles outbreak in University A was likely to be caused by the index case from Uzbekistan. To reduce cases with imported measles, verifying the measles vaccination status of international students and administering preemptive vaccinations are needed.
