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

backgroundEcchordosis physaliphora (EP) is a benign notochordal remnant that is usually asymptomatic; symptomatic cases are extremely rare. Most of the reported symptomatic cases were managed by resection via craniotomy. CASE DESCRIPTION: We report a case of a 20-year-old male presenting with abducens nerve palsy. Magnetic resonance imaging performed on admission demonstrated a mass in the retroclival prepontine location. The patient was treated successfully by endoscopic endonasal trans-sphenoidal surgery (ETSS), his postoperative course was uneventful, and the abducens nerve palsy disappeared.

conclusionETSS has advantages not only for treatment but also for differentiation between EP and intradural chordoma. This is the first case of symptomatic EP successfully treated solely by ETSS.
