Mediating Role of Delay Discounting in the Link Between Depressive Symptoms and Diabetes Onset: Findings from a Prospective Survey of a Community Sample.

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
backgroundThe positive relationship between higher delay discounting, an indicator of increased impulsivity, and reduced engagement in diabetes care has been investigated. However, the association between delay discounting and diabetes onset, likely linked through unhealthy behaviors, has not been well investigated. Additionally, although depression has been linked to an increased risk of diabetes and greater delay discounting, studies examining associations among all three factors are scarce. The present study aimed to determine the association between depressive symptoms and the onset of diabetes, with delay discounting as a mediator of this relationship.
methodsUsing data from a three-phase online prospective survey of a community sample, cross-sectional and longitudinal mediation analyses were conducted to examine diabetes prevalence from Phase 1 and incidence from Phases 2 and 3 as the outcomes, with depressive symptoms at Phase 1 as the independent variable and delay discounting at Phase 1 as the mediator.
resultsDelay discounting was positively associated both with diabetes prevalence (coefficient = 0.170; 95% confidence interval [CI] = 0.066 to 0.278; P = 0.002) and incidence (coefficient = 0.306; 95% CI = 0.098 to 0.540; P = 0.006). Furthermore, through delay discounting, depressive symptoms were indirectly associated with diabetes prevalence (indirect coefficient = 0.091; 95% bootstrap CI = 0.034 to 0.149) and incidence (indirect coefficient = 0.138; 95% bootstrap CI = 0.037 to 0.256), respectively.
conclusionsDelay discounting may increase the risk of diabetes onset by mediating the positive association between depressive symptoms and diabetes onset.
