The relationship between depression and cognitive function among adults with spinal cord injury: a systematic review and meta-analysis.
Synthesis in Spinal cord, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
STUDY
designSystematic review and meta-analysis.
objectivesDespite a growing prevalence of cognitive impairment and depression after spinal cord injury (SCI), evidence of associations between specific cognitive domains and processes with depressive symptoms remains uncertain. This systematic review with meta-analysis aimed to evaluate the relationship between cognitive functions and depressive symptoms in adults with SCI.
methodsThis review was pre-registered with PROSPERO (CRD42024523479). Seven databases were searched from inception to March 2025. Eligible studies assessed depression and cognitive function in adults with SCI and were published in English. Cognitive functions included self-reported subjective cognitive failures and objective cognitive functions assessed by neuropsychological tests. Study quality was assessed via the Newcastle-Ottawa Scale.
resultsTen studies (three cohort, seven cross-sectional; N = 1683 participants) were included, with seven studies eligible for meta-analysis. The pooled results revealed that elevated depressive symptoms are significantly associated with global cognitive impairment, whereas there were no associations with subjective cognitive decline or deficits in specific domains (i.e., executive function, attention, and learning and memory).
conclusionsAdults with SCI who have impaired global cognitive function exhibit higher levels of depressive symptoms. Interventions targeting either depression or cognitive function may yield concomitant benefits on both outcomes, thereby enhancing health-related quality of life of the SCI population. More prospective studies are needed to investigate the relationship between depression severity and specific cognitive domains and to elucidate their potential causal mechanisms.
