Patterns and the Occurrence of KRAS Mutations in Metastatic Colorectal Cancers-a Study from Indian Regional Cancer Centre.
Article in Indian journal of surgical oncology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Mutation analysis of the KRAS oncogene is established as a predictive biomarker in Colorectal cancer (CRC). Many prospective clinical trials have shown that only CRCs with wild-type KRAS respond to anti-epidermal growth factor receptor (EGFR) treatment. Hence, mutation analysis is mandatory before treatment of metastatic CRCs. There are very few studies on the KRAS mutation status in the Indian setting. Hence, this study was done to document the patterns of KRAS mutations in CRCs reporting to a regional cancer centre in South India. Among 150 cases of metastatic colorectal cancer reporting over a period of 20 months, 48 random cases were analyzed for the KRAS mutational status of codons 12 and 13 of the KRAS gene by genomic sequencing. KRAS mutations in codons 12 and 13 were present in 9/48 (18.75%) of all analyzed CRCs. The common types of mutations were glycine to aspartate on codon 12 (p.G12D), glycine to valine on codon 12 (p.G12 V), and glycine to aspartate on codon 13 (p.G13D).
