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

backgroundTo evaluate the associations between magnetic resonance imaging (MRI) findings and pain, disability and quality of life before surgery and up to 5 years after lumbar microdiscectomy. MATERIALS AND

methodsSixty-one patients who underwent one-level lumbar microdiscectomy by the same surgeon participated in this analytic, observational, prospective study. Lumbar spine MRI was performed preoperatively and 5 years postoperatively. Pain, disability and quality of life were measured with VAS, ODI, Roland Morris and SF-36 pre- and up to 5 years postoperatively. Subsequently associations between radiological findings and clinical outcomes were recorded.

resultsBefore surgery patients with disc extrusion or sequestration, with increased thecal sac compression (d > 2/3), with Modic changes (MC) 2 and 3 on the operated level and Pfirrmann grades IV and V on the operated and both adjacent discs presented the worst preoperative clinical outcomes. MC preoperatively were not related with postoperative results, in contrast with the type of disc herniation and thecal sac compression. Preoperative Pfirrmann grade IV and V on the operated and both adjacent discs and postoperative MC 2 and 3 on the operated level were related to poor clinical outcomes 36-60 months post-discectomy.

conclusionsExtrusion or sequestration of the operated disc, increased compression of thecal sac, MC 2 and 3 on the operated level and Pfirrmann grades IV and V on the operated and adjacent discs were associated with the worst clinical outcomes. Nerve root impingement, facet joint arthritis, perineural fibrosis and disc granulation tissue had no effect on clinical scores.
