Surgery for stage IIB-IIIB small cell lung cancer.
Article in World journal of surgical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe NCCN guidelines do not recommend surgery for T3-4N0M0/T1-4N1-2M0 small cell lung cancer (SCLC) due to a lack of evidence.
methodsData of patients with T3-4N0M0/T1-4N1-2M0 SCLC were extracted from the Surveillance, Epidemiology, and End Results (SEER) database to determine the impact of surgery on this population. The Kaplan-Meier method, univariable and multivariable Cox proportional hazard regression, and propensity score matching (PSM) were used to compare the overall survival (OS) between the surgery and non-surgery groups. In addition, we explored whether sublobectomy, lobectomy, and pneumonectomy could provide survival benefits.
resultsIn total, 8572 patients with SCLC treated without surgery and 342 patients treated with surgery were included in this study. The PSM-adjusted hazard ratio (HR, 95% CI) for surgery vs. no surgery, sublobectomy vs. no surgery, lobectomy vs. no surgery, pneumonectomy vs. no surgery, and lobectomy plus adjuvant chemoradiotherapy vs. chemoradiotherapy were 0.71 (0.61-0.82) (P < 0.001), 0.91 (0.70-1.19) (P = 0.488), 0.60 (0.50-0.73) (P < 0.001), 0.57 (0.28-1.16) (P = 0.124), and 0.73 (0.56-0.96) (P = 0.023), respectively. The subgroup analysis demonstrated consistent results.
conclusionsLobectomy improved OS in patients with T3-4N0M0/T1-4N1-2M0 SCLC, while pneumonectomy also demonstrated a tendency to improve OS without statistical significance; however, sublobectomy showed no survival benefit.
