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

Conventional next generation sequencing analysis has provided important insights into cancer genetics. However, the detection of rare (low allele fraction) variants remains difficult because of the error-prone nucleotide changes derived from sequencing/PCR errors. To eliminate the false-positive variants and detect genuine rare variants, sequencing technology combined with molecular barcodes will be useful. Here, we used the newly developed dual-molecular barcode technology (Ion AmpliSeq HD) to analyze somatic mutations in 24 samples (12 tumor tissues and 12 plasma) from 12 patients with biliary-pancreatic and non-small cell lung cancers. We compared the results between next generation sequencing analysis with or without molecular barcode technologies. The variant allele fraction (VAF) between non-molecular barcode and molecular barcode sequencing was correlated in plasma DNA (R
