Characteristics of imported and domestic malaria cases in Gyeonggi Province, Korea.
Article in Epidemiology and health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
objectivesThis study explored 11 years of malaria data from mandatory reporting in Gyeonggi Province, Korea, to provide information for prevention strategies by linkage to nationwide health claims data.
methodsReported malaria cases in Gyeonggi Province from 2011 to 2021 were linked to medical usage data from the National Health Insurance Database. Data about hospitalization, antibiotic prescription and duration, malarial species, and sociodemographic information of the cases were included.
resultsBetween 2011 and 2021, a total of 3,011 malaria cases were reported, consisting of 2,828 domestic (93.9%) and 183 imported (6.1%) cases. Over 80% of the cases involved males, with the majority of patients being in their 20s. Both domestic and imported cases peaked between June and August over the years. Imported cases had a higher hospitalization rate (66.9%) compared to domestically-acquired cases (54.9%). There was a significant variation in treatment rates, with 80.7% of imported cases and 74.6% of domestic cases receiving treatment. For domestic cases, chloroquine combined with primaquine was the most commonly prescribed treatment (77.0%), while atovaquone-proguanil was frequently used for imported cases (25.9%). Plasmodium vivax was the predominant species in domestic cases (94.9%), whereas P. malariae was more common in imported cases (62.3%). The overall number of reported malaria cases declined following a sharp decrease in imported cases in 2020 and 2021.
conclusionsDespite a decreasing trend in malaria cases reported in Gyeonggi Province, imported cases exhibited higher hospitalization rates and different antibiotic prescription and treatment patterns, reflecting the presence of a different malarial species.
