Time frame: Baseline, 3 months, 6 months, 9 months and 12 months
Change From Baseline to Follow-up Visits in Lung Function: Vital Capacity
In calculating the change from baseline to all follow-up visits (3 months, 6 months, 9 months and 12 months) in lung function: Vital Capacity (VC), only participants with values available at baseline and at follow up were considered. At follow up visit the absolute changes of lung function assessment vs baseline value was calculated as: Change in parameter VC = value of parameter VC at follow up visit - value of parameter VC at baseline visit. A positive value of change indicates a better outcome.
Time frame: Baseline, 3 months, 6 months, 9 months and 12 months
Change From Baseline to Follow-up Visits in Lung Function: Forced Vital Capacity (Actual)
In calculating the change from baseline to follow-up visits in lung function: Forced Vital Capacity (FVC), only participants with values available at baseline and at follow up were considered. At follow up visit the absolute changes of lung function assessment vs baseline value was calculated as: Change in parameter FVC = value of parameter FVC at follow up visit - value of parameter FVC at baseline visit. A positive value of change indicates a better outcome.
Time frame: Baseline, 3 months, 6 months, 9 months and 12 months
Change From Baseline to Follow-up Visits in Lung Function: Forced Vital Capacity (Predicted)
In calculating the change from baseline to follow-up visits in lung function: Forced Vital Capacity (FVC), only participants with values available at baseline and at follow up were considered. At follow up visit the absolute changes of lung function assessment vs baseline value was calculated as: Change in parameter FVC = value of parameter FVC at follow up visit - value of parameter FVC at baseline visit. A positive value of change indicates a better outcome. The value of FVC % of predicted is a relevant parameter to understand and classify the severity of the disease at the diagnosis and to follow up patients during the treatment (i.e. annual rate decline of FVC \>10% is a predictor of high rate of mortality).

Health Related Quality of Life Variation Measured With Saint George's Respiratory Questionnaire
Health Related Quality of Life (HRQoL) variation measured with Saint George's Respiratory Questionnaire (SGRQ), developed to measure health in chronic airflow limitation. It is a disease-specific instrument designed to measure health impairment in terms of impact on overall health, daily life, and perceived well-being in participants with obstructive airways disease. Three component scores (symptoms, activity and impacts on daily life) and a total score were calculated, with lower scores corresponding to better health. The Total score is calculated by summing all positive responses in the questionnaire and expressing the result as a percentage of overall impairment where 100 represents worst possible health status and 0 indicates best possible health status.
Time frame: Baseline, 6 months and 12 months
HRQoL Variation Measured With EuroQol Descriptive System
The quality of life was evaluated by the EuroQol 5-dimension 5-level (EQ-5D-5L) a standardized measure of health status developed by EuroQol Group to provide a simple generic measure of health status for clinical and economic evaluation. EQ-5D-5L was filled in by participants, it was easy from a cognitive point of view, since it took only few minutes for filling. EQ-5D-5L consists of 2 sections: "EQ-5D descriptive system" and EQ visual analogue scale (EQ VAS). The EQ-5D-5L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Time frame: Baseline, 6 months and 12 months
HRQoL Measured With EQ VAS
The quality of life was evaluated by the EQ-5D-5L a standardized measure of health status developed by EuroQol Group to provide a simple generic measure of health status for clinical and economic evaluation. EQ-5D-5L consists of 2 sections: "EQ-5D descriptive system" and EQ VAS. The EQ VAS indicate the health status self-assessed by the participants on a visual analogue scale from 0 to 100, where 100 is the "best imaginable health state" and 0 the "worst imaginable health state". It can be used as a quantitative measure of health as judged by participants.
Time frame: Baseline, 6 months and 12 months
Health Care Resource Consumption From Diagnosis up to End of 12 Months Follow-up According to the Italian National Health Service (INHS)
The health care sector-related costs at diagnosis and from diagnosis up to the end of 12-month follow-up according to the INHS point of view, was carried out in a two-step approach: (i)First of all the resource consumption exclusively related to both IPF, IPF exacerbations and IPF-related adverse events since diagnosis was collected or estimated and then (ii) A monetary value was assigned to the collected or estimated resource consumption. Health care resource consumption was computed during observational period in terms of number of (inward and day-hospital) hospitalizations and number of Intensive Care Unit (ICU) admissions.
Time frame: Up to 12 months
