The Impact of Visual Impairment on Healthcare Use among Four Medical Institution Types: A Nationwide Retrospective Cohort Study in Korea.
Article in Yonsei medical journal, 2023. 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
purposeThe aim of this study was to determine the effect of visual impairment (VI) onset on the use of healthcare services across four types of institutions in South Korea. MATERIALS AND
methodsWe utilized data from the National Health Insurance Service database from 2006 to 2015 for 714 persons who experienced VI onset in 2009-2012 and for 2856 matched persons for a 1:4 ratio of matching controls. We compared trends in healthcare use and expenditures for eye diseases at clinics, hospitals, general hospitals, and tertiary teaching hospitals using 3 years of data prior to and after the onset of VI.
resultsThe inpatient and outpatient healthcare expenditures of individuals with VI were higher than those without VI, peaking at the pre-VI onset period in tertiary teaching hospitals. During the pre-VI onset period, the proportion of healthcare expenditures attributed to eye diseases ranged 11%-40.8% among individuals with VI, but 1.9%-11% among individuals without VI at the four types of institutions. The differences in healthcare use between the pre- and post-VI periods were primarily observed in tertiary teaching hospitals for inpatient care. There was a peak in utilization of outpatient care in the year preceding VI onset at tertiary teaching hospitals, clinics, and hospitals, but there was a decrease in outpatient care over time during the post-VI period.
conclusionOur findings suggest economic burden of healthcare in tertiary teaching hospitals during pre-VI onset period and a potential lack of regular management and continuity of care in post-VI periods.
