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

backgroundSegmentectomy for well-selected early stage non-small-cell lung carcinoma (NSCLC) has been shown to have similar oncologic outcomes and survival to lobectomy. However, these data are based on the presumption that the disease is node negative. Few data exist regarding the risk factors for and the outcomes of patients with disease treated with segmentectomy that is found to be node positive. We sought to determine the risk factors for and outcomes of clinical stage I NSCLC patients who are treated with segmentectomy but are determined to be node positive. PATIENTS AND

methodsWe queried patients with clinical stage I NSCLC ≤ 3 cm within the National Cancer Data Base between 2004 and 2014 who were treated with segmentectomy or lobectomy and found to have positive nodes. Kaplan-Meier curves with log-rank tests were used to compare overall survival (OS) between segmentectomy and lobectomy. For comparison only, segmentectomy patients with pathologically node-negative disease were identified to determine predictors of node positivity after segmentectomy via multivariable logistic regression.

resultsA total of 4556 patients with node-positive disease were identified, comprising 115 segmentectomy patients and 4441 lobectomy patients. Multivariable analysis identified increasing tumor size, squamous-cell histology, and increasing number lymph nodes sampled as significant predictors of node positivity after segmentectomy. There was no difference in OS between segmentectomy and lobectomy, with 3-year OS rates of 66.3% and 68.1%, respectively (P = .723).

conclusionThere are discrete risk factors for discovering positive nodes after segmentectomy. Segmentectomy is associated with similar OS compared to lobectomy for clinical stage I NSCLC found to be node positive.
