The lesser the better? A systematic review and meta-analysis of resection strategy in lung neuroendocrine 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
introductionLung neuroendocrine tumors (LNETs) are rare, with surgical resection as the mainstay of treatment, although the optimal extent remains uncertain. Herein, we present the first meta-analysis to assess the effect of resection extent (lobar vs. sub-lobar) on overall survival.
methodsWe conducted a systematic review of the literature to identify studies comparing overall survival following lobectomy versus sub-lobar resection in LNETs. An inverse-variance meta-analysis was performed, and a Cox regression model was applied to reconstructed time-to-event data estimated from published Kaplan-Meier curves to generate pooled survival estimates.
resultsSix studies encompassing 3,700 patients (lobectomy, n = 2,409; sub-lobar resection, n = 1,291) were included in the final analysis. The pooled 5-year overall survival for the entire cohort was 78.8% (95% CI, 76.6-81.1). No statistically significant difference in overall survival was observed between lobectomy and sub-lobar resection (HR = 1.21; 95% CI, 0.80-1.83; I
conclusionIn this first meta-analysis of surgical resection for LNETs, sub-lobar resection and lobectomy showed no clear difference in overall survival. Adequate lymph node assessment remains essential, irrespective of the surgical approach.
