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
objectivesAmyotrophic lateral sclerosis (ALS) is a rare, progressive, and fatal disease that impacts the lives of affected individuals and their caregivers. Informal caregivers play a crucial role in supporting people with ALS (pwALS), yet they face major challenges. This study aims to analyze caregiver burden and health status among informal caregivers of pwALS in Portugal.
methodsA cross-sectional survey-based study was conducted with adult informal caregivers of pwALS in Portugal, recruited through the Portuguese ALS patient association and healthcare professionals. Data included sociodemographics, caregiving activities, caregiver health (SF-36), patient functional status (ALSFRS-R), and caregiver burden (ZBI).
resultsThe study included 113 caregivers. Most were female (61.9%) and the partner (65.5%) or offspring (23.9%) of the pwALS. A quarter of caregivers received no social benefits. Mean ZBI was 32 ± 14.8, with most reporting mild to moderate burden. On the SF-36, general health was 51.1 ± 19.8, with mental health (55 [40; 70]) and vitality (43.8 [31.3; 56.3]) particularly impaired. ZBI scores correlated positively with caregiving hours ( SIGNIFICANCE OF
resultsCaregivers experienced mild to moderate burden, with impaired mental health and vitality, but preserved physical functioning. A higher burden was linked with lower quality of life, poorer sleep, and greater patient disability. These findings underline the need for targeted education and training to support caregivers of pwALS.
