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

Purpose: This study compared laminectomy and hemilaminectomy for resection of spinal (sHBs), evaluating extent of resection, 12-month postoperative functional outcomes, perioperative complications overall, with particular attention to postoperative bleeding. Material and methods: This retrospective international multicenter study included 280 primary sHB patients from 13 neuro-oncological centers who underwent either laminectomy (n = 125) or hemilaminectomy (n = 155). The endpoints were the extent of resection, functional outcomes at 12 months, and postoperative bleeding requiring retreatment. Multivariable logistic regression analysis was performed to determine independent risk factors associated with these outcomes. Results: The rate of complete resection was similar between both surgical approaches, with 86.4% in the laminectomy group and 90.3% in the hemilaminectomy group ( Conclusion: Laminectomy and hemilaminectomy result in comparable outcomes of sHB. Tumors affecting multiple spinal segments are associated with an increased risk of postoperative bleeding, while combined intra- and extramedullary growth, impaired preoperative functioning and non-lumbar location were associated with incomplete resection. Given the comparable outcomes, the selection of the surgical approach may be guided by surgeon preference and individual patient anatomy.
