Association between medical complications according to continuity of care and medication adherence in patients with hypertension in Korea: a national population-based cohort study.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesTo analyse the differences in hypertensive complications according to continuity of care (COC) and medication adherence in patients with hypertension.
designA national population-based retrospective cohort study.
settingSecondary data analysis using National insurance claims data at all levels of hospitals in South Korea.
participantsA total of 102 519 patients diagnosed with hypertension were included in this study. PRIMARY OUTCOME MEASURES: The levels of COC and medication adherence were estimated within the initial 2 years of the follow-up period, and the incidence of medical complications was estimated within the subsequent 16 years. We used the level of COC to measure COC and the medication possession ratio (MPR) to measure medication adherence.
resultsThe average level of COC in the hypertension group was 0.8112. The average proportion of the MPR in the hypertension group was 73.3%. COC in patients with hypertension showed varying results: the low COC group had a 1.14-fold increased risk of medical complications compared with the high COC group. In terms of the level of MPR in patients with hypertension, the 0%-19% MPR group had a 1.5-fold risk of medical complications relative to the 80%-100% MPR group.
conclusionsIn patients with hypertension, high COC and medication adherence for the first 2 years of diagnosis can help prevent medical complications and promote patients' health. Therefore, effective strategies to improve COC and medication adherence are required. Future research should include some factors that may affect the incidence of hypertensive complications, such as familial aggregation, and hazard stratification by the level of blood pressure, which were not considered in this study. Therefore, there may be residual confounding and still room for improvement.
