The role of wedge resection and lymph node examination in stage IA lung carcinoid tumors.

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.
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
Background: Current guidelines recommend anatomical resection and mediastinal lymph node resection for stage I to IIIA pulmonary carcinoids (PCs). The role of wedge resection in stage IA PCs remains controversial, previous studies focused on typical carcinoids (TCs) while differentiating histological subtypes preoperatively is not easy. We aimed to study the effect of wedge resection and lymph node examination (LNE) in patients with stage IA PCs. Methods: Patients who underwent anatomical and wedge resection for stage T1N0M0 lung carcinoid tumors between 2004 and 2019 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were also divided into a non-LNE group and an LNE group. Kaplan-Meier analysis and the log-rank test were used to calculate and compare overall survival (OS). Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to balance the variables between groups. Univariate and multivariate Cox proportional hazard models were developed to determine prognostic factors. Results: A total of 2,029 patients with bronchopulmonary carcinoid tumors were included in this study, 1,450 underwent lobectomy, 147 underwent segmentectomy and 432 underwent wedge resection. Initially, 5-year survival differed marginally between wedge and anatomical resection (91% Conclusions: For early-stage PC, wedge resection was not inferior to anatomical resection in terms of OS, while LNE significantly increased the survival in both multivariate and matched studies. The relationship between surgical extent and survival in the unadjusted study may be attributed to the lower rate of LNE in wedge resection. Our findings support wedge resection with emphasis on LNE in early-stage PCs.
