The role of oxytocin in mediating the relationships between social factors and chemotherapy-associated cognitive decline in female patients with breast cancer.

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
While chemotherapy can cause debilitating side effects, social support, particularly that of an intimate partner, can be protective. This study examined the relationships between couple satisfaction and chemotherapy-associated subjective and objective cognitive decline in a cohort of breast cancer patients, in addition to the roles of other social factors. Because of oxytocin's role in social bonding and cognition, circulating oxytocin and oxytocin receptor gene expression in peripheral blood mononuclear cells were investigated as potential mediators. Partnered breast cancer patients (n = 48) completed cognitive assessments and provided blood samples at 3 timepoints: pre-chemotherapy, during chemotherapy, and post-chemotherapy. Participants completed a retrospective couple satisfaction questionnaire, provided information about partner duration as well as other social factors (e.g., number of people in the household, number of dependents under 18), and completed a retrospective perceived general social support questionnaire. Analyses were completed using linear mixed effects and regression models. More satisfaction in an intimate relationship related to both less subjective and objective cognitive decline over chemotherapy. Similarly, higher perceived social support related to less overall objective cognitive decline over chemotherapy, though this relationship was less robust than that observed with high couple satisfaction. Remarkably, circulating oxytocin decreased over chemotherapy but was only associated with partner duration and not with cognitive measures. This study suggests a potential benefit of social-directed interventions for the treatment of cognitive side effects of chemotherapy, either from an intimate partner or more generally. Furthermore, understanding biological mechanisms is important to develop novel preventative and interventional therapies to mitigate the adverse side effects of chemotherapy.
