Caregiver Burden and Neuro-Oncology Patient Function: Impacts on Relationship Quality.
Article in Psycho-oncology, 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
backgroundPrior work has identified the protective effects of relationship quality on cancer outcomes. However, less work has focused on how the cancer experience can change relationship quality.
aimsTo describe neuro-oncology patient-caregiver relationship quality over time and identify the impact of caregiver burden and patient physical and cognitive function on perceptions of relationship quality.
methodsThis is a secondary analysis of data obtained at enrollment and 8 weeks. Actor-partner interdependence models of patient and caregiver ratings of their relationship to each other (Couples Satisfaction Index) over time also included baseline measures of patient cognitive and physical function (Neuro-QOL), caregiver burden (Zarit), and change in these measures.
resultsData from 124 neuro-oncology patient-caregiver dyads were analyzed. Relationship quality at both time points, on average, indicated non-distressed relationships, but patients rated relationship quality significantly better than caregivers. Both rated relationship quality significantly worse over time (p values < 0.022). At baseline, caregiver burden was significantly negatively associated with patient (p = 0.014) and caregiver relationship quality (p < 0.001). Patient and caregiver baseline relationship quality predicted their own 8-week scores (actor effect; p values < 0.001). Baseline patient cognitive function (p = 0.011) and change in patient cognitive function (p = 0.039) were positively associated with 8-week patient relationship quality. Change in caregiver burden was negatively associated with 8-week caregiver relationship quality (p < 0.001).
conclusionsPrior research has largely focused on relationship quality as a resource, but factors associated with the cancer experience may impact perceptions of relationship quality. Lowering caregiver burden may be beneficial to preserving this important coping resource.
