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

objectiveBevacizumab was currently available for nonsquamous non-small-cell lung cancer (NSqNSCLC) patients and has been studied in several randomized controlled trials (RCTs) for treatment of these patients. This meta-analysis summarizes the most up-to-date evidences regarding the effects and adverse reactions of bevacizumab in the treatment of NSqNSCLC patients.

methodsThe authors searched for RCTs from electronic database including PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. Experimental arm was defined as the bevacizumab-containing group and the control arm as the bevacizumab-free group. Data of objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and adverse reactions were synthetically extracted. A protocol for this meta-analysis has been registered on PROSPERO (http://www.crd.york.ac.uk/prospero).

resultsTen RCTs that involved a total of 3134 patients were included. The experimental group was associated with significant superior ORR (RR 1.63, 95% CI 1.24 to 2.14,

conclusionThis meta-analysis showed that bevacizumab could increase ORR, OS, and prolonged PFS for treatment of NSqNSCLC patients. However, no significant improvement in DCR was observed and bevacizumab could increase the rate of hypertension and hemorrhagic events. Bevacizumab was an acceptable option for NSqNSCLC patients.
