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

purposeGermline mutations of LKB1 (also known as SKT11; locus 19p13.3) cause the occurrence of autosomal dominant Peutz-Jeghers syndrome (PJS). Nearly half of the non-small cell lung cancer (NSCLC) cell lines and one-third of lung adenocarcinoma in Caucasian patients have an LKB1 mutation.

methodsThis study examined the mutational hot spots of the LKB1 gene in surgical resectable lung adenocarcinoma. Exons 1, 6, and 7 of the LKB1 gene were sequenced in 174 Japanese patients with lung adenocarcinoma (including 157 men and 17 women).

resultsOnly five patients had LKB1 gene alterations (2.9%). All of them were male smokers, and no LKB1 mutation was observed in any of the females. The details of LKB1 alterations were: one 5 bp deletion in intron 5, one Gly to Phe substitution at codon 279 of exon 6, and three Pro to Leu substitutions at codon 281 of exon 6. The P281L alteration and 5 bp deletion in the intron 5 were found to be germline polymorphisms. The G279F was confirmed to be a novel somatic mutation. None of the five patients with an LKB1 alteration showed either an EGFR or K-ras mutation.

conclusionThe LKB1 gene alteration is rare in Japanese patients with lung adenocarcinoma, and is generally limited to male smokers.
