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
purposeTo examine the relationship between intimate partner (IP) caregiver strain with health and family outcomes in military couples with service members and veterans (SMV) experiencing chronic symptoms following traumatic brain injury (TBI).
methodsParticipants included 202 military couples (N = 404) classified into two groups: [1] Caregiving (169 dyads) and [2] Non-Caregiving (33 dyads). The Caregiving group was further classified into [1a] High Caregiver Strain (61 dyads) and [1b] Low Caregiver Strain (86 dyads) groups; excluding 22 dyads to maximize group distinction. Dyads completed measures of physical, psychological, social, caregiving, neurobehavioral, and/or family outcomes.
resultsIPs in the High Caregiver Strain group reported significantly worse scores on health and family outcome measures compared to IPs in the Low Caregiver Strain and Non-Caregiving groups (p<.05, d=0.57-1.97). SMVs of IPs in the High Caregiver Strain Group reported worse scores on outcome measures compared to SMVs of IPs in the Low Caregiver Strain and Non-Caregiving Groups (p<.05, d=0.33-0.1.60). High caregiver strain was associated with assisting SMVs with greater difficulty performing activities (p<.05, d=0.44-0.75) and providing care more hours per day (p<.001, PR = 1.90), but not TBI severity (p=.272, PR = 1.66). A higher prevalence of dyads in the High Caregiver Strain group reported clinically elevated symptoms (≥ 60T) on the health and family outcome measures (11.5%-92.0%).
conclusionCaregiver strain was strongly associated with health and family outcomes in military couples with SMVs experiencing chronic symptoms post-TBI. More attention to the relationship between IP caregiver strain, SMV chronic symptoms, and health and family outcomes in military families is required.
