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
backgroundSuicide remains a critical global public health issue, and the coronavirus disease 2019 (COVID-19) pandemic has intensified mental health challenges, potentially increasing suicide risk. This study aimed to analyze the changes in mental health networks of high-risk suicide groups in Korea before and after the COVID-19 pandemic.
methodsUsing data from the Korean Cohort for the Model Predicting Suicide and Suicide-Related Behavior, we analyzed 1,179 participants, including individuals with recent suicide attempts and those experiencing suicidal ideation. Network analysis was conducted using EBICglasso algorithms separately for men and women before and after the COVID-19 pandemic, to examine the relationships between key mental health variables including depression (Patient Health Questionnaire-9), anxiety (Beck Anxiety Inventory), stress (Stress Questionnaire for Korean National Health and Nutrition Examination Survey-Short Form), impulsivity (Barratt Impulsiveness Scale-11), and suicidal ideation (Columbia-Suicide Severity Rating Scale).
resultsAfter the pandemic, significant increases in the severity and intensity of suicidal ideation were observed in both sexes (
conclusionThe COVID-19 pandemic has led to structural changes in the mental health network of high-risk suicide groups, with anxiety emerging as a more central factor in women and depression in men, highlighting them as key intervention targets. These findings underscore the need for tailored mental health strategies to mitigate suicide risk in populations affected by the pandemic.
