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

BACKGROUND AND

objectivesThe risks of postoperative risk of epilepsy after a craniotomy is widely believed to be raised. A study is warranted to quantify the risks for any neurosurgical indication. In this unselected register-based nationwide cohort study with virtually complete follow-up, the short-term and long-term cumulative risks of postoperative de novo epilepsy for all major neurosurgical indications were estimated.

methodsThe study was based on 8948 first-time craniotomy patients in Denmark 1 January 2005 to 31 December 2015 with follow-up until 31 December 2016. The patients were classified according to their underlying neurosurgical pathology. Patients with preoperative epilepsy were excluded. The postcraniotomy risks of de novo epilepsy were estimated using the Aalen-Johansen estimator in a multistate model.

resultsThe overall cumulative 1-year risk of postcraniotomy de novo epilepsy was 13.9% (95% CI 13.2 to 14.6). For patients with intracranial tumour the cumulative 1-year risk was 15.4% (95% CI 14.4 to 16.5), for spontaneous intracranial haemorrhage 11.3% (95% CI 10.1 to 12.6), for traumatic intracranial haemorrhage 11.1% (95% CI 9.6 to 12.9), for cerebral abscess 27.6% (95% CI 22.8 to 33.5) and for congenital malformations 3.8% (95% CI 1.3 to 11.7). The 6-month, 1-year and 5-year risks for all major indications by specific subtypes are provided.

conclusionsThe cumulative risk of de novo epilepsy following craniotomy is high for patients with any indication for craniotomy, as compared with the background population. The results provide comprehensive data to support future recommendations regarding prophylactic antiepileptic treatment and driving restrictions.
