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

backgroundThe efficacy of curative-intent pulmonary resection for non-small cell lung cancer (NSCLC) patients with certain types of oligometastases, particularly brain and adrenal metastases, has previously been described. We investigated the outcomes of curative-intent pulmonary resection for NSCLC patients with synchronous isolated bone metastases, which have been less clear to date.

methodsWe retrospectively reviewed the clinical and pathological records of 41 patients with NSCLC and synchronous isolated bone metastases who underwent radical treatments (surgery and/or chemotherapy and/or radiotherapy) for both their primary tumors and bone metastases at the National Hospital Organization, Hokkaido Cancer Center, between 2008 and 2013.

resultsNine of the 41 patients underwent pulmonary primary tumor resection; the rate of clinical N0-1 disease among these 9 patients (100%) was significantly higher than that among the 32 patients who did not undergo resection (34.4%). The five-year overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) rates of the nine patients who underwent pulmonary resection were 66.7%, 55.6%, and 44.4%, respectively. On multivariate analysis, the predictors of longer OS among all 41 patients were primary site resection [hazard ratio (HR) =4.18, 95% CI, 1.20-14.6, P=0.025] and epidermal growth factor receptor (EGFR) mutation (HR =3.30, 95% CI, 1.08-10.1, P=0.036). The former was also a predictor of longer PFS (HR =3.75, 95% CI, 1.27-11.0, P=0.016).

conclusionsPatients with clinical N0-1 NSCLC and synchronous isolated bone metastases may achieve longer survival rates following primary lung tumor resection.
