Associations of Cancer-Related Posttraumatic Stress Symptoms and Gender With Health Behaviors Among Caregivers of Adult Patients With Colorectal Cancer.
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
backgroundThe life-threatening nature of cancer can precipitate posttraumatic stress symptoms (PTSS) in family caregivers. PTSS can lead to unhealthy coping and maladaptive health behaviors.
aimsWe explored the extent to which PTSS are associated with health behaviors of caregivers and the moderating role of gender.
methodsSpousal caregivers (N = 144) of patients who were newly diagnosed with colorectal cancer were enrolled. The sample was comprised of mostly Hispanic, middle-aged, and female caregivers. Four types of cancer-related PTSS (intrusions, avoidance, negative alterations in cognitions and mood, and alterations in arousal and reactivity) and health behaviors (substance use and improper healthcare utilization) were self-reported. Study hypotheses were tested using logistic and negative binomial regression models.
resultsCaregivers overall reported higher alcohol use than CDC recommendations. Male caregivers reported greater alcohol use and more improper healthcare utilization compared with their female counterparts (p < 0.03). Among female caregivers only, greater avoidance was associated with less improper healthcare utilization, and greater negative alterations in cognitions and mood was associated with more improper healthcare utilization (p ≤ 0.01).
conclusionsFindings that male caregivers are more vulnerable to alcohol use and improper healthcare utilization highlight the need for healthy lifestyle coping interventions tailored specifically to male caregivers. In contrast, female caregivers who exhibit elevated negative alterations in cognitions and mood are at greater risk for improper healthcare utilization than male counterparts. Findings suggest that interventions targeting cancer-related PTSS may help improve engagement of proper healthcare utilization and reduce the risk for premature morbidity among female caregivers.
