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
Background: While there have been studies indicating a connection between insufficient levels of vitamin D and persistent low back pain (LBP), there is still a lack of definitive evidence. The primary objective of this study was to evaluate the correlation between vitamin D intake, and associated factors with chronic lower back pain. Methods: This research utilized a cross-sectional study design. Data were collected from the records of patients presenting with LBP at our institute from February 2024 to June 2024. We included patients who were presented at our institute with chronic LBP and no associated comorbidities. Data were collected from the records of the patients, including age (years), weight (kg), height (cm), hips (cm), duration of sun exposure (hours/day), areas of the skin exposed to the sun (% body), dietary vitamin D supplementation, and pain severity using a numerical rating scale. The Oswestry low back disability questionnaire was utilized to assess the disability and pain originating from the low back. Results: A total of 392 participants were included in the present retrospective study with a median (range) age of 37 years (10-86). Their median (range) weight, height, and hips were 79 (25-110), 168 (130-190), and 36 (26-65), respectively. The presence of low back disability and discomfort was discovered to have a positive correlation with parameters such as older age, increased body weight, broader hips, longer duration of sun exposure, larger surface area of the body exposed to the sun, and higher reported levels of pain severity. Moreover, a significant link was found between inadequate intake of vitamin D and higher degrees of impairment in patients with LBP. Conclusion: Insufficient vitamin D intake was prevalent among individuals with chronic LBP and was significantly associated with higher levels of disability. Factors such as older age, increased weight, and greater pain severity are also correlated with greater functional impairment. These findings suggest a potential role of vitamin D in the assessment and management of chronic LBP.
