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.

Abstract

The prognosis for patients with recurrent glioblastomas (GBMs) is dismal, with a median survival of 3-6 months. We performed a phase II trial of low-dose continuous (metronomic) treatment using temozolomide (TMZ) for recurrent GBMs. TMZ-refractory patients with GBM who experienced disease recurrence or progression during or after the cyclic treatment schedule of TMZ after surgery and standard radiotherapy were eligible. This phase II trial included 2 cohorts of patients. The initial cohort, comprising 10 patients, received TMZ at 40 mg/m(2) everyday. After this regimen seemed safe and effective, the metronomic schedule was changed to 50 mg/m(2) everyday. The second cohort, comprising 28 patients, received TMZ at 50 mg/m(2) everyday. The 6-month progression-free survival in all 38 patients was 32.5% (95% CI: 29.3%-35.8%) and the 6-month overall survival was 56.0% (95% CI: 36.2%-75.8%). One patient developed a grade III neutropenia, grade II thrombocytopenia in 3 patients, and grade II increase of liver enzyme (GOT/GPT) in 3 patients. Of all patients included in this study, 4 patients were withdrawn from this study because of side effects including sustained hematological disorders, cryptococcal infection, and cellulitis. In a response group, quality of life measured with short form-36 was well preserved, when compared with the pretreatment status. Metronomic treatment of TMZ is an effective treatment for recurrent GBM that is even refractory to conventional treatment of TMZ and has acceptable toxicity.
