Objective The aim of this study was to establish a nomogram graph model to accurately predict the venous thromboembolism (VTE) risk probability in the general population with lung cancer. Methods Based on data from patients with lung cancer in Chongqing University Cancer Hospital of China, the independent risk factors of VTE were identified by the logistic univariable and multivariable analysis and were integrated to construct a nomogram, which was validated internally. The predictive effectiveness of the nomogram was evaluated by the receiver operating characteristic curve (ROC) and calibration curve. Results A total of 3398 lung cancer patients were included for analysis. The nomogram incorporated eleven independent VTE risk factors including karnofsky performance scale (KPS), stage of cancer, varicosity, chronic obstructive pulmonary disease (COPD), central venous catheter (CVC), albumin, prothrombin time (PT), leukocyte counts, epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), dexamethasone, and bevacizumab. The C-index of the nomogram model was 0.843 and 0.791 in the training and validation cohort, respectively, demonstrating good discriminative power. The calibration plots of the nomogram revealed excellent agreement between the predicted and actual probabilities. Conclusions We established and validated a novel nomogram for predicting the risk of VTE in patients with lung cancer. The nomogram model could precisely estimate the VTE risk of individual lung cancer patients and identify high-risk patients who are in need of a specific anticoagulation treatment strategy.

Drawing on the narcissism literature and social information processing theory, we theorized and examined a serial mediation model linking leader narcissism with team voice behavior through leader voice solicitation and team voice climate. We tested our hypotheses using data collected from a time-lagged and multisource survey of 223 frontline employees in 60 teams at a large manufacturing organization. The results indicated that leader narcissism had a negatively indirect effect on team voice climate via leader voice solicitation. Team voice climate positively predicted team voice behavior, and the indirect effects of leader narcissism via leader voice solicitation and team voice climate on team voice behavior were significantly negative. In this paper, we discuss the theoretical implications of our findings for both the narcissism literature and the voice literature, along with their practical implications.
