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

backgroundDue to their rarity, the clinicopathological characteristics and prognostic factors of spinal cord gliomas are still unclear. Here, we aimed to clarify these issues in a cohort of 108 spinal cord astrocytomas.

methodsWe characterized the clinicopathological characteristics, including 2016 World Health Organization (WHO) grade, age, sex, location, segment length, resection, pre- and postsurgery, Modified McCormick Scale (MMS), radio- and chemotherapy, and Ki-67 and H3 K27M mutations, in 108 spinal cord astrocytomas through heatmaps. The Cox regression analysis and Kaplan-Meier curves were used to study the prognostic value of these clinicopathological features.

resultsThere are a total 38 H3 K27M-mutant tumors, including 31 cases with histological grade II/III tumors. The age of low-grade astrocytoma patients (WHO grade I/II, n = 54) was significantly younger (27.0 vs 35.5 years, P = .001) than those with high-grade tumors (WHO grade III/IV, n = 54). All patients underwent surgical resection with neurophysiological monitoring, and the surgery did not result in significant changes in MMS. The presurgery MMS was associated with overall survival in the high-grade subgroup (P = .008) but not in the low-grade subgroup (P = .312). While, the high content of resection improved the survival of only patients with low-grade astrocytomas (P = .016) but not those with high-grade astrocytomas (P = .475). Both the low-grade and high-grade astrocytomas had no obvious benefit from neither adjuvant chemotherapy nor radiotherapy (all P > .05).

conclusionsWe characterized the clinicopathological characteristics and their prognostic values in 108 spinal cord astrocytomas, which could help with evidence-based management of spinal cord astrocytomas.
