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

Cigarette smoking represents for the highest risk-factor for non-small cell lung cancer (NSCLC), and a growing body of evidence suggested that smoking was associated with a high recurrence and poor therapeutic response of NSCLC as well. On the other hand, epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs), such as gefitinib, has been proved to be an efficient and safe strategy for treating NSCLC. Although accumulating clinical data suggested that smoking history might influence the therapeutic effects of EGFR-TKIs even in NSCLC patients harboring sensitive EGFR mutation, the exact effects of cigarette smoking on the efficacy of EGFR-TKIs treatment in NSCLC patients remain exclusive. In this study, we firstly identified the adverse effect of smoking exposure on the efficacy of EGFR-TKIs treatment against lung adenocarcinoma in mutation-positive patients by retrospective analysis of clinical data. The hypo-responsiveness of smoking patients on the therapy was accompanied with persistent activation of EGFR-downstream signal molecules ERK1/2 and AKT, which could not be inhibited by gefitinib and thus lead to the failure of EGFR-TKIs treatment. Based on our in vitro data, it was also found that long-term cigarette smoking extract (CSE) exposure induced epithelial-mesenchymal transition (EMT), which might also contribute to acquired resistance to EGFR-TKIs. Taken together, our findings suggested that cigarette smoking negatively regulated the clinical outcome of EGFR-TKIs therapy in lung adenocarcinoma patients, which was correlated with the activation of EGFR signaling and the induction of EMT.
