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

backgroundAlthough the majority of current medulloblastoma adjuvant therapy protocols treat patients with ≥ 1.5 cm

objectivesWe sought to synthesize the body of literature on EOR and survival to determine if a definitive association exists. DATA SOURCES/ELIGIBILITY CRITERIA: A PubMed search was conducted for the terms "medulloblastoma" combined with "extent of resection," "overall survival," "progression free survival," "gross total resection," "near total resection," "partial resection," or "subtotal resection." Studies that performed a statistical analysis of EOR and survival were included.

resultsSixteen articles including 1489 patients found a statistically significant association between EOR and survival, 20 articles including 2335 patients did not find a significant association between EOR and survival, and 14 articles including 2950 patients had mixed results. The three articles that accounted for molecular subgroup found varying associations between EOR and progression free survival, while no association was found between EOR and overall survival. LIMITATIONS: This review is limited by inconsistent definitions of EOR, the retrospective nature of the articles analyzed, and infrequent use of multivariate statistical analyses.

conclusionsThe prognostic importance of EOR for medulloblastoma is unclear and warrants re-evaluation, particularly in the context of molecular subgrouping.
