    Table_2_Effects of alcohol-related problems on the costs of frequent emergency department use: an economic analysis of a case–control study in Spain.pdf by Clara Oliveras (10828899)

    Published 2024
    “…Clinical data and direct healthcare costs for a single ED visit were obtained by a retrospective review of the first electronic medical register. Costs and duration of stay were compared between cases and controls using paired-samples t-tests, and ED users with and without alcohol-related problems were compared using bivariate (independent-samples t-tests, one-way analysis of variance, Chi square tests, and multiple linear regression) and multivariate analyses (multiple linear regression models with backward stepwise selection algorithm, and dependent variable: total mean direct costs).…”
