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

backgroundThe first generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), gefitinib and erlotinib, have become the standard first-line treatment for non-small-cell lung cancer (NSCLC) patients with EGFR mutation. However, there was no pooled analysis focused on the usage of the second-generation TKI, afatinib, in advanced EGFR-positive NSCLC patients after failure of first generation TKIs. Therefore, a meta-analysis was conducted to solve the above question.

methodsElectronic databases were searched for eligible literatures. ORR (objective response rate), DCR (disease controlled rate), PFS (progression-free survival), OS (overall survival) and primary grade 3/4 adverse events were pooled with the corresponding 95% confidence interval using R software. Sensitivity analyses and heterogeneity were quantitatively evaluated.

resultsA total of 545 EGFR-positive patients were available for analysis from five studies after detailed screening from 909 relevant studies. The pooled ORR and DCR of afatinib in EGFR-positive patients after failure of the first generation EGFR-TKIs were 0.12 (0.08-0.19) and 0.60 (0.53-0.68), respectively. Besides, the 6 m-PFS rate, 1 y-PFS rate and 6 m-OS rate were 0.26 (0.22-0.30), 0.08 (0.06-0.10) and 0.74 (0.56-0.86). The grade 3/4 rate of diarrhea and that of skin deformity were 0.23 (0.10-0.46) and 0.14 (0.05-0.33), respectively. Sensitivity analyses revealed similar results with lower heterogeneity.

conclusionsConsidering the efficacy, toxicity and current availability, afatinib could be a therapeutic option for advanced EGFR mutated NSCLC patients after the failure of 1st-generation TKIs.
