Sublobar resection versus lobectomy for patients with stage T1-2N0M0 pulmonary typical carcinoid tumours: a population-based propensity score matching analysis.
Article in Interactive cardiovascular and thoracic surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
objectivesIt is widely accepted that surgical resection of localized pulmonary typical carcinoid (TC) tumours remains the primary curative modality. However, the optimal extent of resection remains controversial. This study aimed to investigate the survival rates of patients with stage T1-2N0M0 TC tumours who underwent sublobar resection or lobectomy.
methodsWe queried the Surveillance, Epidemiology, and End Results database for patients who underwent surgery after being diagnosed with stage T1-2N0M0 TCs from 2004 to 2016. Propensity score matching (PSM) analysis was used to equalize the baseline characteristics between the sublobar resection group and the lobectomy group. Kaplan-Meier analysis and the Cox proportional hazard model were performed for survival analysis.
resultsOf the 2469 patients included, 658 (26.65%) underwent sublobar resection and 1811 (73.35%) underwent lobectomy. All 2469 patients were analysed with PSM and, following PSM, 812 patients were included in the final analysis and divided into 2 groups of 406 patients. In the matched cohort, Kaplan-Meier analysis demonstrated no significant difference in survival curves between the sublobar resection and lobectomy groups in patients with stage T1-2N0M0 TC tumours [5-year overall survival (OS) = 90.78% vs 93.30%; hazard ratio 1.18, 95% confidence interval: 0.77-1.80; P = 0.505]. Subgroup analysis by tumour size showed that the sublobar resection group was identical to the lobectomy group in OS for tumours ≤3.0 cm. In addition, no difference in OS between surgical groups was observed in any subgroups. In the multivariable Cox analysis, age ≤65 years, female sex, married status and adequate lymph node assessment (≥5) were associated with improved OS, whereas the extent of resection was not.
conclusionsSublobar resection seems to be associated with similar survival to lobectomy for stage T1-2N0M0 TC tumours if lymph node assessment is performed adequately. This analysis suggests that sublobar resection should be considered an appropriate alternative for stage T1-2N0M0 TC tumours. However, further validations are needed in large, multicentre prospective studies.
