Treatment-related serious adverse events and fatal adverse events with regorafenib in cancer patients: a meta-analysis of phase 3 randomized controlled trials.

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.
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
Regorafenib (Stivarga) is an oral small-molecule multikinase inhibitor commonly used against a variety of cancers. We performed a meta-analysis of all phase 3 randomized controlled trials (RCTs) of regorafenib to quantify the increased risk of SAEs and FAEs. We carried out a systematic search of electronic databases for studies published from inception to February 2017 without any restrictions. Eligibility criteria included phase 3 RCTs of tumors comparing regorafenib, alone or in combination with non-targeted chemotherapy (regorafenib arm) versus placebo or non-targeted chemotherapy (control arm). Data on SAEs and FAEs were extracted from each study and pooled to determine the overall incidence, relative risks (RRs) and 95% confidence intervals (CIs). A total of four phase 3 RCTs involving 1736 cancer patients met the eligibility criteria and were included. The overall incidence of SAEs and FAEs with regorafenib were 0.23 (95%CI, 0.05-0.40) and 0.02 (95%CI, 0.01-0.03), respectively. Compared with control, the summary RR of developing a regorafenib-related SAE was 1.60 (95%CI, 0.95-2.68, P=0.07), the summary RR of developing a regorafenib-related FAE was 1.71 (95%CI, 0.69-4.24, P=0.25). No evidence was found for the association between regorafenib and higher risk of SAEs and FAEs. This association varied significantly with cancer types (P=0.02) for SAEs but no evidence of heterogeneity was found for FAEs. This meta-analysis demonstrates no evidence for the association between regorafenib and higher risk of SAEs and FAEs. This analysis will be important when considering the trade-off of regorafenib treatment during clinical decision-making.
