[Effectiveness of EGFR-TKIs versus chemotherapy as first-line treatment for advanced non-small cell lung cancer: a meta-analysis].
Synthesis in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
BACKGROUND AND
objectiveEpidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) has been used for the first-line treatment of non-small cell lung cancer (NSCLC) and has shown good clinical effects. However, some patients fail to benefit from this treatment. The aim of this study is to analyze whether or not clinical-selected patients (Asian, adenocarcinoma histology, non-smoking) and EGFR mutation-selected patients benefit from EGFR-TKIs or chemotherapy. Our results could be used as basis to guide clinical therapy.
methodsRandomized controlled trials evaluating the efficacy of EGFR-TKIs versus chemotherapy as first-line treatments of NSCLC were obtained from electronic databases, namely, PubMed, Embase, American Society of Clinical Oncology (ASCO), European Society for Medical Oncology, and China Biology Medicine disc. Assessment, data collection, and statistical analysis were performed according to Cochrane Handbook 5.1.0.
resultsA total of 14 randomized controlled trials with 5,000 patients were included in this study. Compared with the chemotherapy group, EGFR-TKI therapy group in EGFR mutation-selected NSCLC patients showed a higher response rate (RR=2.31; 95%CI: 1.88-2.84) and more significant improvement in progression free survival (PFS; HR=0.39; 95%CI: 0.30-0.49); by contrast, no significant difference was observed in overall survival (OS; HR=0.99; 95%CI: 0.84-1.16). The response rate of clinical-selected patients treated with EGFR-TKI significantly increased (RR=1.30; 95%CI: 1.15-1.47) compared with that of the patients treated with chemotherapy; PFS (HR=0.93; 95%CI: 0.58-1.49) and OS (HR=0.91; 95%CI: 0.81-1.02) of the two groups did not significantly differ. Likewise, the PFS and the OS of the unselected patients in the EGFR-TKI treatment group and the chemotherapy group did not significantly differ, although the OS of the former was shorter than that of the latter.
conclusionsEGFR mutation-selected patients received more benefits from EGFR-TKI first-line treatment than other treatments. First-line EGFR-TKI treatment was recommended for clinically selected patients who were unsuitable for themotherapy. By comparison, first-line EGFR-TKI treatment was not a suitable choice for unselected patients.
