All-cause and cause-specific mortality in gambling disorder: Evidence from a nation-wide matched and sibling cohort study in Taiwan.

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
BACKGROUND AND
aimsGambling disorder (GD) has been linked to suicidal ideation and suicide deaths; however, evidence on all-cause and cause-specific mortality-particularly in Asian populations-remains limited. Using a retrospective cohort study based on nationwide matched and sibling cohort, we investigated all-cause and cause-specific mortality risk in patients with GD. DESIGN, SETTING AND
participantsA retrospective cohort study was conducted using 2000-2022 data from Taiwan's National Health Insurance Research Database. A cohort of 961 individuals diagnosed with GD was identified. An age- and sex-matched control cohort (n = 3,844) and an unaffected sibling cohort (n = 675) were constructed. Cumulative survival was illustrated using Kaplan-Meier curves. MEASUREMENTS: Cox regression models estimated crude and adjusted hazard ratios (AHR) for all-cause, natural-cause and unnatural-cause (accidents and suicides) mortality risks. Covariates for adjustment included sociodemographic factors, physical and psychiatric comorbidities and familial confounding.
findingsOver a mean follow-up of 8 years, GD was associated with elevated all-cause mortality risk [AHR 1.20, 95% confidence interval (CI) = 0.90-1.61] driven by statistically significantly elevated risk of unnatural mortality (AHR 6.15, 95% CI = 3.44-10.98) and especially suicide mortality (AHR 10.03, 95% CI = 4.71-21.33). Risk of natural mortality was statistically significantly lower in GD patients (AHR 0.66, 95% CI = 0.45-0.96). Sibling cohort analysis revealed a similar trend (all-cause mortality: AHR 1.70, 95% CI = 0.67-4.28; unnatural cause mortality: AHR 8.65, 95% CI = 1.62-46.22; suicide mortality: AHR 7.24, 95% CI = 0.74-70.59; natural cause mortality: AHR 0.48, 95% CI = 0.13-1.73). Results remained consistent after adjustment for individual psychiatric comorbidities.
conclusionsGambling disorder patients in Taiwan appear to have a statistically significantly increased risk of unnatural-cause mortality and especially suicide mortality compared with matched controls. Policies and clinical interventions for treating GD patients should focus on suicide prevention to reduce mortality in this population.
