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
purposeThe Neck Disability Index (NDI) is used to evaluate patients with cervical spine disease. However, few reports have defined the cut-off values of the NDI. The purpose of this study was to identify the cut-off values of and factors with a negative impact on NDI.
methodsA total of 487 volunteers were divided into three groups based on disability: none, mild, and disabled. The cut-off values of the NDI were determined using receiver-operating characteristic curves. After these groups were divided based on sex and age adjustment was performed, the factors with a negative impact on NDI were investigated using multiple logistic regression analysis.
resultsGroups none, mild, and disabled included 207, 186, and 94 volunteers, respectively. The cut-off values of the NDI in each group were 0-5, 6-17, and ≥ 18%, respectively. After adjusting for age, groups none, mild, and disabled had 65, 56, and 23 males, respectively, and 92, 103, and 56 females, respectively. In multiple logistic regression analysis, the factors with a negative impact on NDI in males were manual work (odds ratio [OR] 1.924), higher T1 slope minus cervical lordosis (OR 1.043), and higher C2-7 sagittal vertical axis (OR 1.029, P < 0.05). Among females, the factors were hand-grip strength (OR 0.936), body fat percentage (OR 0.942), and sporting activity (OR 0.456, P < 0.05).
conclusionDeterioration in NDI was associated with cervical spinal malalignment and manual labor in males and lack of physical activity and sarcopenia in females. These slides can be retrieved under Electronic Supplementary Material.
