Non-standard employment, paid sick leave, and income loss during COVID-19 self-isolation: cross-sectional findings from South Korea.

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
backgroundTesting and isolation are crucial measures to control infectious diseases, yet limited research has examined inequalities in the impact of these measures on individual earnings. This study aimed to assess whether income loss during COVID-19 self-isolation varied by workers' employment type in South Korea.
methodsCross-sectional data were collected via online surveys from March to September 2022. The analysis included 1,064 employees who tested positive for COVID-19, aged 20-65. Employment types were categorized as standard or non-standard, with the latter encompassing temporary, part-time, and atypical arrangements (multi-party employment arrangements or dependent self-employment). Multivariate logistic regression was used to examine the association between employment type and income loss during COVID-19 self-isolation. The mediating roles of access to paid sick leave and the level of compensation provided were assessed through a counterfactual framework.
resultsOverall, 30.5% of participants experienced decreased earnings while self-isolating due to COVID-19 infection. After adjusting for covariates, non-standard workers were three times more likely (adjusted odds ratio 2.96 [95% confidence interval 2.10-4.15]) to experience this income loss compared to standard employees. Among non-standard worker subgroups, atypical workers faced the highest risk (4.06 [2.52-6.55]), followed by part-time (3.02 [1.78-5.13]) and temporary workers (2.25 [1.44-3.51]). This disparity in income loss was attributed to two distinct pathways: non-standard workers having less access to paid sick leave (coverage gap) and, when such leave was available, being more likely than standard workers to receive compensation that was insufficient to maintain pre-isolation earnings (adequacy gap). Our mediation analysis indicated that these two pathways contributed almost equally (51% and 49%, respectively) to the observed income disparities.
conclusionBoth expanding access to paid sick leave and ensuring adequate compensation rates are needed to enable non-standard workers to comply with pandemic control measures without fear of income loss.
