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

Identifying specific factors affecting psychological resilience could be instrumental in developing new therapeutic strategies for improving and maintaining mental and physical health. To achieve this, an adequate measure of psychological resilience is essential. We studied the psychometric properties of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10) across three population-based cohorts. The study included adult Danish individuals in the Danish Blood Donor Study (DBDS, N = 57,031), and the Icelandic cohorts Stress-And-Gene Analysis cohort (SAGA, N = 27,236), and COVID-19 National Resilience cohort (C19-Resilience, N = 20,373). Exploratory factor analysis revealed a consistent one-factor fit across cohorts. The scale demonstrated good internal consistency (Cronbach's alpha: 0.88-0.90) and longitudinal stability (Spearman correlation coefficients in DBDS: 0.71 across 1.5 years, 0.66 across two years). Mean CD-RISC-10 scores were consistent with previously reported scores in European populations. Lower scores were observed among participants with probable major depressive disorder, and higher scores were found with increasing age. Further evidence for construct validity was revealed as CD-RISC-10 scores moderated the association between financial trouble and depressive symptoms across all cohorts. Psychometric properties of the CD-RISC-10 were similar among women and men. Our findings support the use of the CD-RISC-10 as a reliable and valid unidimensional measure of psychological resilience in Danish and Icelandic populations.
