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

backgroundTo assess management patterns and outcome in patients with glioblastoma multiforme (GBM) treated during 2008-2010 in Spain.

methodsRetrospective analysis of clinical, therapeutic, and survival data collected through filled questionnaires from patients with histologically confirmed GBM diagnosed in 19 Spanish hospitals.

resultsWe identified 834 patients (23% aged >70 years). Surgical resection was achieved in 66% of patients, although the extent of surgery was confirmed by postoperative MRI in only 41%. There were major postoperative complications in 14% of patients, and age was the only independent predictor (Odds ratio [OR], 1.03; 95% confidence interval [CI],1.01-1.05; P = .006). After surgery, 57% received radiotherapy (RT) with concomitant and adjuvant temozolomide, 21% received other regimens, and 22% were not further treated. In patients treated with surgical resection, RT, and chemotherapy (n = 396), initiation of RT ≤42 days was associated with longer progression-free survival (hazard ratio [HR], 0.8; 95% CI, 0.64-0.99; P = .042) but not with overall survival (HR, 0.79; 95% CI, 0.62-1.00; P = .055). Only 32% of patients older than 70 years received RT with concomitant and adjuvant temozolomide. The median survival in this group was 10.8 months (95% CI, 6.8-14.9 months), compared with 17.0 months (95% CI, 15.5-18.4 months; P = .034) among younger patients with GBM treated with the same regimen.

conclusionsIn a community setting, 57% of all patients with GBM and only 32% of older patients received RT with concomitant and adjuvant temozolomide. In patients with surgical resection who were eligible for chemoradiation, initiation of RT ≤42 days was associated with better progression-free survival.
