The calibration curve displayed consistency between the actual and predictive values in both training and validation groups. The prognostic nomogram with the extent of VPI could offer an accurate risk evaluation for patients with NSCLC. Independent external validation of this research should be conducted in the future.

Therefore, this study aimed to assess the rates and time to symptom improvement and resolution in patients with moderate-to-severe AECB who were given prulifloxacin in the routine care in Greece. This observational, prospective study, conducted in 15 hospital-based clinics across Greece, enrolled outpatients >40 years old, with moderate-to-severe AECB, for whom the physician had decided to initiate treatment with prulifloxacin. Data were collected at prulifloxacin onset (baseline), 7-10 days after baseline, and at least 28 days after therapy completion. Between 23 November 2015 and 27 January 2018, 305 patients (males 76.4%; mean (standard deviation) (SD) age 69.7 (9.8) years; Anthonisen type I/II 94.8%; chronic bronchitis duration >10 years 24.9%) were consecutively enrolled. At baseline, >80% had increased sputum volume, cough, dyspnoea, and sputum purulence. Prulifloxacin improved symptoms in 99.7% of the patients after a mean (SD) of 5.47 (3.57) days, while symptoms fully recovered after a mean (SD) of 10.22 (5.00) days in 95.4%. The rate of
