Should KRAS mutation still be used as a routine predictor of response to EGFR-TKIs in advanced non-small-cell lung cancer? A revaluation based on meta-analysis.

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
purposeRegarding the controversial investigations characterizing the role of KRAS status for predicting patients' response to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in advanced non-small-cell lung cancer (NSCLC), we conducted a meta-analysis in unselected patients and a further subset analysis in EGFR wild-type advanced NSCLC to get a more accurate evaluation.
methodsWe did systematically searches following the retrieval strategies. The end points were overall survival (OS), progression-free survival (PFS), and overall response rate (ORR).
resultsTwelve prospective intervention trials comprised of 1,859 unselected advanced NSCLC patients were identified. KRAS mutation was associated with shorter OS and PFS [hazard ratio (HR) 2.09, 95 % confidence interval (CI) 1.56-2.80; HR 1.82, 95 % CI 1.50-2.20] and lower ORR (relative ratio 0.25, 95 % CI 0.11-0.59) in unselected advanced NSCLC. After subgroup analysis, the association with survival was strengthened in second- or later-line EGFR-TKIs treatment group, with an HR of 2.45 for OS (95 % CI 1.27-4.74) and 1.86 for PFS (95 % CI 1.51-2.29), while the association with response to EGFR-TKIs became nonsignificant (P = 0.153). Four retrospective studies on the role of KRAS status in EGFR wild-type advanced NSCLC were deemed eligible and presented that KRAS mutation was associated with none of the outcomes in EGFR wild-type patients treated with EGFR-TKIs.
conclusionsIn unselected advanced NSCLC patients, KRAS mutations could be used as a potential negative predictor of clinical benefit from EGFR-TKIs. However, KRAS testing is of limited value to identify patients for EGFR-TKIs when EGFR status is considered.
