| Incidence Probability of Progression to Pulmonary Fibrosing-Interstitial Lung Disease (PF-ILDs) | At 6, 12, 18 and 24 months after the index date, defined between 01-Jan-2013 and 6 months before 28-May-2020 | The cumulative incidence probability is the estimate of the risk a patient will experience by 6, 12, 18 and 24 months after the second diagnosis of fibrosing ILD (index date) of progression to PF-ILDs. It is the complement of the Kaplan-Meier estimates. The Greenwood's variance estimate was used to calculate the 95% confidence interval. Disease progression was defined as 3 or more pulmonary function tests within 365 days, 3 or more tomographies within 365 days, 1 or more claims for oxygen therapy during follow-up, 1 or more respiratory hospitalizations during follow-up, 1 or more claims for palliative care during follow-up, 1 or more lung transplant during follow-up, 1 or more claims for immunosuppressive drugs during follow-up, 1 or more claims for oral corticosteroid during follow-up, and 1 or more claims for Nintedanib during follow-up. Follow-up was between 1-Jan-2013 to 28-May-2020, the last encounter in Medical Data Vision database, or in-hospital death, whichever occurs first. |

Recruitment details
Retrospective cohort study using the Medical Data Vision (MDV) database to study progression to Progressive Fibrosing Interstitial Lung Disease (PF-ILDs) in a real-world setting in Japan. Data was extracted for the period of 01-Jan-2012 to 28-May-2020 for patients presenting pre-specified ILDs that received a second diagnosis of a fibrosing ILD other than Idiopathic Pulmonary Fibrosis (IPF) between 01-Jan-2013 to 6 months before 28-May-2020.
Pre-assignment details
Patients that met all inclusion criteria and none of the exclusion criteria were followed from the day after of the second diagnosis of a fibrosing ILD other than IPF - index date - until the end of study period (28-May-2020), the last encounter in the MDV database or in-hospital death, whichever occurs first.

Outcome results
Incidence Probability of Progression to Pulmonary Fibrosing-Interstitial Lung Disease (PF-ILDs)
The cumulative incidence probability is the estimate of the risk a patient will experience by 6, 12, 18 and 24 months after the second diagnosis of fibrosing ILD (index date) of progression to PF-ILDs. It is the complement of the Kaplan-Meier estimates. The Greenwood's variance estimate was used to calculate the 95% confidence interval. Disease progression was defined as 3 or more pulmonary function tests within 365 days, 3 or more tomographies within 365 days, 1 or more claims for oxygen therapy during follow-up, 1 or more respiratory hospitalizations during follow-up, 1 or more claims for palliative care during follow-up, 1 or more lung transplant during follow-up, 1 or more claims for immunosuppressive drugs during follow-up, 1 or more claims for oral corticosteroid during follow-up, and 1 or more claims for Nintedanib during follow-up. Follow-up was between 1-Jan-2013 to 28-May-2020, the last encounter in Medical Data Vision database, or in-hospital death, whichever occurs first.
Time frame: At 6, 12, 18 and 24 months after the index date, defined between 01-Jan-2013 and 6 months before 28-May-2020
Population: Full analysis set: Patients in Japan with data available in the Medical Data Vision (MDV) database, between 01-Jan-2012 to 28-May-2020, who met all inclusion criteria and none of the exclusion criteria. The number of patients analyzed displays the number of patients at risk of progression at the time of interest.
