Development and validation of a predictive model for postoperative residual low back pain following percutaneous kyphoplasty or percutaneous vertebroplasty.

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
objectiveTo identify risk factors for persistent postoperative low back pain in patients undergoing percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) and develop a predictive nomogram model.
methodThis retrospective study included 749 patients with osteoporotic vertebral compression fractures (OVCF), who were allocated into a modeling cohort (n = 524) and a validation cohort (n = 225). Patients with a Visual Analog Scale (VAS) score > 4 at one month postoperatively were classified into the residual low back pain group, while the rest were classified as the normal group. Univariate and multivariate logistic regression analyses were performed to identify factors associated with postoperative back pain, and subsequently, a nomogram model was constructed for predictive validation.
resultsIn the modeling cohort, 61 patients reported persistent low back pain at one month after surgery. According to univariate and LASSO-Logistic regression analyses, the number of fractured vertebrae, bone cement distribution, bone cement leakage, 5-hydroxyvitamin D
conclusionNumber of fractured vertebrae, insufficient bone cement distribution over the fracture line, bone cement leakage, serum 25-(OH)D
