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
Purpose: This study aimed to examine the correlation between diffusion tensor imaging (DTI) parameters (fractional anisotropy, FA; apparent diffusion coefficient, ADC) and clinical outcomes (neck disability index, NDI; visual analog scale, VAS) in cervical spondylotic radiculopathy (CSR) patients following percutaneous cervical nucleoplasty (PCN), respectively. Methods: This is a cross-sectional study. We collected clinical data from 30 patients with CSR who underwent DTI before and 3 months after PCN. The FA and ADC were derived from DTI. The NDI and VAS were used to evaluate the clinical symptoms preoperatively, at 3 months postoperatively, and at the final follow-up. By setting multiple region of interest areas, the cervical nerve roots were delineated using fiber tractography. The Pearson correlation analysis was used to investigate the relationship between DTI values and clinical severity. Results: NDI and VAS scores after PCN were significantly improved compared with preoperative scores (P < 0.05). The FA and ADC values after PCN were significantly different from the preoperative values (P < 0.001). The Pearson correlation revealed that preoperative FA values were strongly correlated with preoperative NDI scores (r = -0.802, P < 0.001), whereas postoperative FA values were strongly correlated with postoperative NDI scores (r = -0.804, P < 0.001). Furthermore, postoperative FA values were strongly correlated with NDI scores at the final follow-up (r = -0.805, P < 0.001). However, no significant difference was observed between the DTI and VAS scores. Similarly, no significant correlations were observed between ADC values and NDI scores pre- and postoperatively. Conclusion: DTI is an imaging method that helps identify the clinical functional status of patients with CSR after PCN. The FA value can be used as a potential predictor of patient prognosis and are strongly negatively correlated with NDI scores. However, the long-term predictive effect warrants further investigation.
