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

Direct oral anticoagulants (DOACs) are increasingly prescribed in treatment of cancer-associated thrombosis, but limited data exist regarding safety of DOACs in patients with brain metastases. We aimed to determine the incidence of intracranial hemorrhage (ICH) in patients with brain metastases receiving DOACs or low-molecular-weight heparin (LMWH) for venous thromboembolism or atrial fibrillation. An international 2-center retrospective cohort study was designed. Follow-up started on the first day of concomitant anticoagulation and brain tumor diagnosis. At least 2 brain imaging studies were mandated. The primary outcome was the cumulative incidence of any spontaneous ICH at 12-month follow-up with death as a competing risk. Major ICH was defined as spontaneous, ≥10 mL in volume, symptomatic, or requiring surgical intervention. Imaging studies were centrally reviewed by a neuroradiologist blinded for anticoagulant type. PANWARDS (platelets, albumin, no congestive heart failure, warfarin, age, race, diastolic blood pressure, stroke) score for prediction of ICH was calculated. We included 96 patients with brain metastases (41 DOAC, 55 LMWH). The 12-month cumulative incidence of major ICH was 5.1% in DOAC-treated patients and 11.1% in those treated with LMWH (hazard ratio [HR], 0.45; 95% confidence interval [CI], 0.09-2.21). When anticoagulation was analyzed as a time-varying covariate, the risk of any ICH did not differ between DOAC- and LMWH-treated patients (HR, 0.98; 95% CI, 0.28-3.40). PANWARDS score was not associated with ICH risk. This international 2-center study suggests comparable safety of LMWH and DOACs in patients with brain metastases.
