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

introductionGiven the uncertain generalizability of recent clinical trial data, a comparative effectiveness analysis evaluating the long-term survival of "real world" patients may clarify the role of lobectomy and sublobar resection (segmentectomy or wedge resection) in the treatment of early stage NSCLC.

methodsAdult patients undergoing lung resection for clinical stage IA NSCLC (≤2 cm) between 2012 and 2022 were identified from the Society of Thoracic Surgeons General Thoracic Surgery Database. Long-term vital status was determined by linkage to the National Death Index and Centers for Medicare & Medicaid Services inpatient data. The primary end point was overall survival (OS); secondary end points included lung cancer-specific survival (LCSS). Stabilized inverse probability weighted Cox regression was used to account for selection bias and derive hazard ratios (HRs) with 95% confidence intervals comparing the lobectomy, segmentectomy, and wedge resection cohorts.

resultsOverall, 32,340 patients with stage IA NSCLC (19,778 lobectomies [OS = 71.9% (5 y), 44.8% (10 y)], 4279 segmentectomies [OS = 69.6%, 44.2%], and 8283 wedge resections [OS = 66.3%, 41.4%]) were evaluated. After risk adjustment, lobectomy was associated with improved OS and LCSS compared with sublobar resection (HR [OS] = 0.87 [0.83-0.92]; HR [LCSS] = 0.84 [0.73-0.97]). Both lobectomy (HR [OS] = 0.84 [0.80-0.88]; HR [LCSS] = 0.72 [0.56-0.93]) and segmentectomy (HR [OS] = 0.88 [0.81-0.95]; HR [LCSS] = 0.77 [0.66-0.89]) were associated with improved survival compared with wedge resection. No differences in OS or LCSS were observed between lobectomy and segmentectomy.

conclusionIn routine clinical practice, lobectomy and segmentectomy are associated with improved OS and LCSS compared with wedge resection for stage IA NSCLC (≤2 cm). These findings highlight the potential gap between trial efficacy and real-world effectiveness.
