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

Lung cancer is a commonly diagnosed cancer. In this era of personalized medicine, genetic predictive models are becoming increasingly important. However, many current predictive models fail verification tests due to small sample sizes and institutional biases. We collected 17 gene expression datasets from public databases to generate our largest training and testing cohorts. After successfully eliminating institutional variations and merging multiple datasets, we generated a training cohort of 1073 and a testing cohort of 659. Using Siggenes, univariate and multivariate analyses, we identified seven gene signatures, and combined them with the clinical parameter age and stage to design the lung cancer prognostic index (LCPI). Using LCPI, we could differentiate lung cancer patients into three risk groups and predict patient survival probabilities at 10 and 15 year post-surgical resection. We extensively verified the predictive ability of LCPI for overall and recurrence free survival using 6 other datasets from five different countries.
