1 · What the graph read from it

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.

2 · The registry

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 influence of vertebral cement augmentation on spinal sagittal balance is unknown. The present study aimed to analyze the changes in total spinal alignment after Kyphoplasty in VCF patients.

methodsThe study involved 21 VCF patients who underwent Kyphoplasty. In all patients, lateral radiographs of the entire spine were taken preoperatively and 1 month after surgery, to measure the pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), sagittal vertical axis (SVA), and spinosacral angle (SSA). These parameters were compared between VCF patients and 30 healthy volunteers. In VCF patients, the parameters were compared before and after Kyphoplasty.

resultsIn VCF patients, preoperative SVA was 7.00 ± 3.9 cm, showing a significant shift to anterior sagittal balance as compared to the healthy group (1.45 ± 2.7 cm) (P < 0.0001). Preoperative SS was smaller and PT was larger in VCF group than in the healthy group (P < 0.05). After Kyphoplasty, SVA decreased to 5.02 ± 2.91 (P = 0.0007) and LL and SSA increased (LL P = 0.028; SSA P = 0.0031). Postoperative decrease of SVA was correlated with the kyphotic change of treated vertebra (r = 0.792, P < 0.01). VAS score decreased from 7.98 ± 1.8 before Kyphoplasty to 2.38 ± 2.3 postoperatively (P < 0.0001).

conclusionsTotal spinal alignment is shifted to anterior sagittal balance in VCF patients. Kyphoplasty plays a role not only in reducing pain associated with fractures but also in improving sagittal imbalance in the treatment of painful vertebral compression fracture.
