The protective role of cognitive reserve in moderating depressive symptomatology in patients with multiple sclerosis.

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 prevalence of cognitive impairment (CI) in Multiple Sclerosis is between 40 and 65% in MS patients, affecting domains like memory, attention, slowed information processing speed, and language. High levels of depression have also been shown to exacerbate cognitive symptoms. However, some studies revealed that greater Cognitive Reserve (CR), protects against cognitive decline in PwMS. This study investigates the role of CR in moderating the effect of depression on cognitive functions in a cohort of 187 Italian PwMS. While acknowledging the influence of anxiety, fatigue, and sleep quality on cognitive performance, our primary focus was on the depression-cognitive function link.
methods187 PwMS (W = 130; mean age = 42.0 years; SD = 12.5), from the Bari University Hospital, underwent testing for semantic fluency (Word List Generation [WLG]), sustained attention and working memory (Paced Auditory Serial Addition Test [PASAT]), Cognitive Reserve level (Cognitive Reserve Index questionnaire [CRIq]), and depressive symptomatology (Beck's Depression Inventory [BDI]; ).
resultsStatistically significant correlations emerged between WLG and CRIq, PASAT and CRIq, WLG and BDI, PASAT and BDI. GLM mediation analyses revealed that the direct effects of depression on PASAT and WLG scores were not statistically significant (p > 0.05). In contrast, the indirect impact (BDI → CR → PASAT and BDI → CR → WLG) was significant (z=-2.29, p < 0.05; z=-2.49; p < 0.05.
conclusionThese results suggest that CR moderates the relationship between depressive symptomatology and sustained attention, and between depressive symptomatology and verbal fluency. The evidence indicates that CR benefits MS patients by alleviating cognitive and depressive symptoms, thereby improving their quality of life.
