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

purposeA prospective study of patients with glioma was carried out. Special attention was paid to the first seizure, to the histology, and to the efficacy and prophylactic role of antiepileptic drugs (AEDs). Prognostic factors were analyzed.

methodsBetween February 1st 2004 and April 1st 2006 patients who underwent surgical treatment at the Neurosurgery Department of Bolzano for primary or recurrent glioma were prospectively followed until April 1st 2007. Seizures at onset occurring in the absence of interictal epileptiform abnormalities were regarded as remote symptomatic seizures and not treated.

resultsSixty-four individuals were registered in the study; epilepsy diagnosis was made in 27 cases and in 24 of these seizures were the onset symptom. The correlation with histological grading showed that seizures were more frequent in low-grade glioma and in secondary glioblastoma. Although epilepsy was less frequent in high-grade glioma, in these patients seizures were more difficult to control. Poor seizure control was associated with motor and sensitive focal seizures and presence of neurological deficit. Patients without epilepsy and not taking AEDs never developed seizures during the follow-up. DISCUSSION: Our study clearly shows that epilepsy is more frequent in low-grade gliomas but seizures are more difficult to control in high-grade gliomas. In both cases seizures are a quite exclusive symptom at the onset that never appears during the stable course of the disease. Amongst glioblastoma multiforme (GBM), epilepsy is more frequent in GBM developing through progression from low-grade astrocitoma. Moreover, our study strongly indicates that the prophylactic use of AEDs in glioma is not justified.
