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

BACKGROUND Long-term follow-up results showed that epidural scar formation and adhesion after laminectomy always affected the outcomes of repeat operations. The establishment of a barrier between scar tissue and dura was effective in preventing epidural scar formation. MATERIAL AND METHODS A nano-hydroxyapatite/polyamide66 (n-HA/PA66) artificial lamina was designed and fabricated and used to cover the opened spinal canal in patients who received laminectomy. The visual analogue scale (VAS) and Japanese Orthopedic Association (JOA) Scores, X-ray, computed tomography, and magnetic resonance imaging results were periodically recorded and evaluated. RESULTS All patients were followed up for 4-7 years, with an average period of 5.2 years. The clinical symptoms improved significantly after surgery, as the JOA scores were significantly improved after the operation and maintained to last follow-up when compared with preoperative ones (P<0.05). The vertebral canal became noticeably enlarged, from 16.7±4.7 mm to 32.9±2.2 mm, after surgery and well maintained to 32.1±1.8 mm. The lumbar lordosis was well maintained after surgery. No rupture, absorption, or dislodgement of the n-HA/PA66 lamina was found. MRI showed the spinal canal had the correct morphology, with no stenosis, no obvious scar formation, and no nerve roots or epidural sac compression. CONCLUSIONS The artificial lamina is a reasonable choice for prevention of epidural scar formation after laminectomy, in spite of the results from a small sample of cases.
