Correlation between Vitamin D deficiency and nonspecific chronic low back pain: A retrospective observational study.
Article in Journal of family medicine and primary care, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
contextChronic lower back pain (CLBP) and Vitamin D deficiency are two common conditions presenting to primary care physicians.
aimsTo study the vitamin D status in North Indians presenting with nonspecific CLBP and the correlation between vitamin D levels and pain severity by the Visual Analogue Scale (VAS). SETTINGS AND
designAn observational study. Record of all CLBP patients presenting to the outpatient department in 2019, were analyzed, retrospectively. METHODS AND MATERIALS: All the patients of age 18 to 65 and either sex with nonspecific CLBP were included. Patients were divided into two: Vitamin D deficient (Group 1) and normal (Group 2) with cut off Serum Vitamin D values at 30 ng/mL. Demographic data and Visual Analogue Scale scores (VAS) of both groups were recorded. STATISTICAL ANALYSIS USED: Correlations between Vitamin D values and VAS scores were investigated using the Spearman coefficient, and the results with P of ≤ 0.05 were contemplated significant.
resultsOf total 376 patients with nonspecific CLBP, the majority were adults, females, married, vegetarians, overweight or obese, and had a mean sun exposure time of two hours. Vitamin D deficient Group 1 had 302 (80.32%) patients with significantly lower (
conclusionsThis study indicated a high probability of vitamin D deficiency in the nonspecific CLBP population and a negative correlation between vitamin D status and pain severity.
