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

The aim of this study was to assess the efficacy of the Wallis interspinous device for treating lumbar disc herniation (LDH) as well as to investigate whether the device could reduce the incidence of recurrent herniation in comparison with disc excision alone. A total of 72 patients with LDH were treated with primary discectomy and the Wallis interspinous device was implanted in 36. Clinical outcomes were evaluated with a visual analog scale (VAS) for low back and leg pain and the Oswestry Disability Index (ODI) before and after surgery. The incidence of recurrent disc herniation after the operation was also evaluated. There was a significant improvement (p < 0.01) in the clinical outcomes assessed by the VAS and ODI scores compared with preoperative values in both groups. Up to the final follow-up, there were no significant differences between the two groups in VAS and ODI scores (p > 0.05). In addition, there was no significant difference regarding the incidence of recurrent disc herniation between the two groups (13.9% vs. 16.6%, p > 0.05). Of the patients five underwent second discectomy or fusion surgery. The Wallis interspinous device was unable to improve the already good clinical outcome after discectomy for LDH and prevent or reduce recurrence of herniated disc in the current follow-up interval. Whether the device for should be used for LDH should be carefully considered before surgery.
