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

objectiveTo investigate the prognostic impact of lymph node (LN) dissection on sublobar resection for stage IA non-small cell lung cancer (NSCLC) tumors ≤2 cm.

methodsAll patients who underwent sublobar resection for stage IA NSCLC tumors ≤2 cm were identified from the Surveillance, Epidemiology and End Results database. Patients were classified into no-LN dissection and LN dissection groups, and the latter was subclassified by the extent of LN dissection (1-3 regional LNs or ≥4 regional LNs). These groups were compared in terms of lung cancer-specific survival (LCSS) and overall survival (OS) rates. Propensity score-matched comparative analysis and a Cox regression model were used.

resultsA total of 3269 patients met our criteria, including 1459 (44.6%) who underwent no LN dissection, 891 (27.3%) who underwent dissection of 1 to 3 regional LNs, 919 (28.1%) who underwent dissection of ≥4 regional LNs. Compared with no LN dissection, LN dissection was associated with more favorable LCSS and OS rates in patients who underwent sublobar resection for stage IA tumors ≤2 cm. More extensive regional LN dissection (≥4 regional LNs) was associated with better LCSS and OS rates compared with less extensive regional LN dissection (1 to 3 regional LNs). A multivariable analysis of our patient population revealed independent associations of no LN dissection and less extensive regional LN dissection with poorer LCSS and OS rates compared with overall LN dissection and more extensive regional LN dissection, respectively.

conclusionsThis propensity score-matched analysis reveals an association of LN dissection, particularly more extensive regional LN dissection (≥4 regional LNs), with better survival rates in patients who undergo sublobar resection for stage IA NSCLC tumors ≤2 cm.
