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

backgroundVenous thromboembolism (VTE) occurs in up to 30% of patients with high-grade glioma (HGG). Concern for increased risk of intracranial hemorrhage (ICH) with therapeutic anticoagulation (AC) complicates VTE treatment. Some retrospective studies have reported an increased risk of ICH associated with therapeutic AC; however, effective alternatives to AC are lacking. The aim of our study is to assess the risk of ICH in HGG patients with VTE on low molecular weight heparin (LMWH).

methodsWe performed a retrospective matched cohort study of HGG patients from January 2005 to August 2016. Blinded review of neuroimaging for ICH was performed. For analysis of the primary endpoint, estimates of cumulative incidence (CI) of ICH were calculated using competing risk analysis with death as competing risk; significance testing was performed using the Gray's test. Median survival was estimated using the Kaplan-Meier method.

resultsTwo hundred twenty patients were included, 88 (40%) with VTE treated with LMWH, 22 (10%) with VTE, not on AC, and 110 (50%) without VTE. A total of 43 measurable ICH was recorded: 19 (26%) in LMWH, 3 (14%) in VTE not on AC, and 21 (19%) in non-VTE cohort. No significant difference was observed in the 1-year CI of ICH in the LMWH cohort and non-AC with VTE group (17% vs 9%; Gray's test, P = .36). Among patients without VTE, the 1-year CI of ICH was 13%. Median survival was similar among all 3 cohorts.

conclusionsOur data suggest that therapeutic LMWH is not associated with substantially increased risk of ICH in HGG patients.
