1 · What the graph read from it

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.

2 · The registry

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

backgroundPeople who care for a family member with dementia alongside paid work often experience role conflict. This study explores whether work-care role conflict (WCRC) modifies the effectiveness of Draw Care, an online and culturally adapted carer support intervention.

methodsSecondary exploratory analysis of a single-blind, parallel-group trial (August 2023-November 2024) that compared Draw Care against waitlist control in adult carers from diverse linguistic backgrounds. To formally test whether WCRC moderated the effect of the Draw Care intervention, we ran a full-sample linear mixed model that included a 3-way interaction between time-point, treatment group, and an indicator of WCRC. Work-care role conflict was operationalized as self-report of missed work or reduced productivity due to competing care and employment demands. Outcomes included carer burden, mood, quality of life, and productivity/activity impairment at 6 and 12 weeks.

resultsForty-two of 93 carers reported WCRC. Reductions in caregiver burden due to treatment at 6 weeks (-10.00; 95% CI, -19.70 to -0.31, p = .043) and 12 weeks (-9.56; 95% CI, -18.83 to -0.29, p = .043) were significantly larger in participants with WCRC than without. This moderating effect of WCRC was driven by a robust, absolute reduction in caregiver burden in intervention group participants with WCRC over the initial 6 weeks (-7.19, 95% CI, -12.72 to -1.67, p = .011), with much of this improvement preserved at 12 weeks (-6.85, 95% CI, -12.17 to -1.53, p = .012).

conclusionsWCRC appears to modify the effectiveness of Draw Care, suggesting that the intervention may be particularly helpful for carers navigating role conflict. CLINICAL TRIAL REGISTRATION NUMBER: ACTRN12622000382774 and ACTRN12622000358741.
