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

backgroundThere exists lack of consensus worldwide regarding the most optimal adjuvant therapy regimen in elderly patients with newly-diagnosed glioblastoma (GBM). PURPOSE: To identify the most optimal adjuvant therapy regimen in elderly GBM patients through systematic review and network meta-analysis.

methodsProspective trials randomly assigning elderly GBM patients post-operatively to any adjuvant therapy regimen were included. The primary outcome measure was overall survival. Numbers of events, patients at-risk, and censored patients for survival were estimated from Kaplan-Meier survival curves in the interval of 0-12 months. The total person-time at risk and the mortality × 100 person-months was also estimated. The relative ranking probability of each treatment and rankograms were used to estimate the hierarchy of each intervention in terms of overall survival. The mean rank values and the surface under the cumulative ranking (SUCRA) curves were also calculated.

resultsA systematic literature search identified 1278 abstracts, that were screened to retrieve full-text manuscripts of potentially eligible articles. After detailed assessment, data from 1569 patients in 7 randomized controlled trials (RCTs) treated with one of following regimens was extracted and analyzed: normofractionated radiotherapy (RT) delivered over 5.5-6 weeks; moderately hypofractionated RT (2-3 weeks) either alone or in combination with temozolomide or bevacizumab; extremely hypofractionated RT (1-week); temozolomide monotherapy; and best supportive care alone. In terms of overall survival, moderately hypofractionated RT (3-weeks) with concurrent and adjuvant temozolomide emerged as the best and second-best adjuvant therapy option with 81% probability and 99.1% probability respectively. Using SUCRA, the surface area for moderately hypofractionated RT (3-weeks) with concurrent and adjuvant temozolomide reached almost 100%, confirming it as the best intervention. As expected, best supportive care alone was ranked as the worst treatment strategy.

conclusionModerately hypofractionated RT (3-weeks) with concurrent and adjuvant temozolomide is the most optimal and preferred adjuvant therapeutic regimen in elderly GBM.
