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

purposeMyxopapillary ependymoma (MPE) is the most frequent tumor affecting the medullary conus. The surgical therapeutic management is still debated and only few studies have focused on the postoperative clinical outcome of patients. This study aimed to demonstrate long-term postoperative outcome and to assess the predictive factors of recurrence as well as the clinical evolution of these patients.

methodsFrom 1984 to 2019, in four French centers, 101 adult patients diagnosed with MPE were retrospectively included.

resultsMedian age at surgery was 39 years. Median tumor size was 50 mm and lesions were multifocal in 13% of patients. All patients benefited from surgery and one patient received postoperative radiotherapy. Gross total resection was obtained in 75% of cases. Sixteen percent of patients presented recurrence after a median follow-up of 70 months. Progression free survival at 5 and 10 years were respectively estimated at 83% and 79%. After multivariable analysis, sacral localization, and subtotal resection were shown to be independently associated with tumor recurrence. 85% of the patients had a favorable evolution concerning pain. 12% of the patients presented a postoperative deterioration of sphincter function and 4% of motor function.

conclusionSurgery alone is an acceptable option for MPE patients. Patients with sacral location or incomplete resection are at high risk of recurrence and should be carefully monitored.
