The impact of minimum wage increase on suicidal ideation in South Korea: a difference-in-differences analysis using nationally representative panel data.
Article in Social psychiatry and psychiatric epidemiology, 2024. 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
backgroundSouth Korea had the highest suicide rates in the OECD and one of the largest (16.4%) increases in the minimum wage in 2018. Prior studies have provided evidence that increases in minimum wage reduce suicide rates in the population, but no study examined the effects of the policy change on individual-level suicidal behaviour.
methodsOur study sample was built using the 2015-2019 waves of the Korean Welfare Panel Survey, a population-representative longitudinal survey. The sample consisted of 5146 participants, including those earning above minimum wage (control) and minimum wage earners (treatment) based on their 2018/19 earnings. The outcome of the study was suicidal ideation, which is an important precursor to other suicidal behaviours, and was captured using self-reported measures. We examined the impact of the 2018 minimum wage hike in Korea on suicidal ideation, using a difference-in-differences design.
resultsThe minimum wage increase was associated with a 1.6% points reduction (95% CI: -2.8% to -0.5%) in self-reported suicidal ideation. Stronger policy effects were shown among women and older age groups.
conclusionsOur study demonstrates that public policies employing a population-based approach, such as increasing minimum wages, could serve as an effective intervention to mitigate suicidal ideation among low-income workers.
