Large Cell Neuroendocrine Tumor Size >3 cm Negatively Impacts Long-Term Outcomes After R0 Resection.
Article in World journal of surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundMinimal knowledge exists regarding the outcome, prognosis and optimal treatment strategy for patients with pulmonary large cell neuroendocrine carcinomas (LCNEC) due to their rarity. We aimed to identify factors affecting survival and recurrence after resection to inform current treatment strategies.
methodsWe retrospectively reviewed 72 patients who had undergone a curative resection for LCNEC in 8 centers between 2000 and 2015. Univariable and multivariable analyses were performed to identify the factors influencing recurrence, disease-specific survival and overall survival. These included age, gender, previous malignancy, ECOG performance status, symptoms at diagnosis, extent of resection, extent of lymphadenectomy, additional chemo- and/or radiotherapy, tumor location, tumor size, pT, pleural invasion, pN and pStage.
resultsMedian follow-up was 47 (95%CI 41-79) months; 5-year disease-specific and overall survival rates were 57.6% (95%CI 41.3-70.9) and 47.4% (95%CI 32.3-61.1). There were 22 systemic recurrences and 12 loco-regional recurrences. Tumor size was an independent prognostic factor for systemic recurrence [HR: 1.20 (95%CI 1.01-1.41); p = 0.03] with a threshold value of 3 cm (AUC = 0.71). For tumors ≤3 cm and >3 cm, 5-year freedom from systemic recurrence was 79.2% (95%CI 43.6-93.6) and 38.2% (95%CI 20.6-55.6) (p < 0.001) and 5-year disease-specific survival was 60.7% (95%CI 35.1-78.8) and 54.2% (95%CI 32.6-71.6) (p = 0.31), respectively.
conclusionsA large proportion of patients with surgically resected LCNEC will develop systemic recurrence after resection. Patients with tumors >3 cm have a significantly higher rate of systemic recurrence suggesting that adjuvant chemotherapy should be considered after complete resection of LCNEC >3 cm, even in the absence of nodal involvement.
