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

Supratentorial extraventricular ependymoma (STEE) and supratentorial intraventricular ependymoma (STIE) are two subsets of supratentorial ependymoma (SE). These two subsets have similar gene features and only differ in original sites: STEE occurs in the brain parenchyma, and STIE is located in ventricles and surrounded by cerebral spinal fluid. The present study aims to depict the diversities of these two subsets and elucidate the potential effects of the anatomic site on the tumor with the same type, grade, and molecular features. Sixty-six consecutive adult SE patients from 2008 to 2021 were enrolled in our study. Clinical data, pathological features, and long-term outcomes were analyzed retrospectively. Results demonstrated that adult STEE presented with a higher proportion of WHO grade 3 (P = .028) and higher Ki-67 index (≥10%) (P = .019) compared to adult STIE. Survival analysis demonstrated that patients of grade 3 STEE exhibited a significantly longer overall survival (OS) than patients of grade 3 STIE (median OS, 24.4 months vs. 13.0 months; P = .004). Grade 2 (hazard ratio (HR) = 0.217; P < .001) and gross total resection (GTR) (HR = 0.156; P < .001) were identified as favorable prognostic factors for all adult SE. The STEE was also associated with a lesser hazard of death for patients of grade 3 on multivariate analysis (HR = 0.263; P = .047). These findings suggested that the extraventricular site was an indicator for higher grade and better prognosis in adult supratentorial ependymoma.
