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

backgroundA retained medullary cord (RMC) is an uncommon, closed spinal dysraphism characterized by a robust extended cord-like structure that extends continuously from the conus medullaris to the dural cul-de-sac. There have been six reports of RMC extending to a related sacral subcutaneous meningocele. To the best of authors' knowledge, the combination of retained medullary cord with thoracic arachnoid cyst has never been reported in the literature. CASE PRESENTATION: We present a case of the above combination in a 2-year-old child who underwent resection of RMC and fenestration of associated anteriorly placed arachnoid cyst under neuromonitoring. It is prudent to delineate functional and nonfunctional cord segment with neuromonitoring before truncating. The child improved significantly after surgery, and at 1-year follow-up, the child was able to walk with support.

conclusionSurgery for RMC involves delineation with neuromonitoring and resection of the nonfunctional cord. Fenestration of the arachnoid cyst must be included in surgical planning, which can be performed as a staged procedure or at same setting.
