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

backgroundRoutine testing of baseline

methodsWe compared the diagnostic performance, sensitivity and specificity of three methods, namely MALDI-TOF mass spectrometry (MS), Allele-Specific Real Time PCR (AS-PCR), droplet digital PCR (ddPCR). Ultra-deep next generation sequencing (NGS) validation of T790M-mutant NSCLCs was performed using SiRe

resultsBaseline T790M occurred in 17% of the tumors. Intermediately sensitive techniques such as MALDI-TOF MS (detection limit of T790M ≥5%) allow to detect T790M in 2% of cases exhibiting mutant-allele fractions ranging from 11.5% to 17%. Median overall survival (OS) in these patients was poor (7.3 months) and progression free survival (PFS) was of 3.3 months in patients treated with a 1st generation EGFR TKI. The remaining T790M-positive cases showed very low mutant-allele fractions ranging from 0.07% to 0.38% and required highly sensitive methods such as ddPCR and NGS to be identified. All these cases showed a concurrent sensitizing
