Among those studied, 9,492—or 16.5 percent—used inhaled corticosteroids. The team divided them into high-, medium-, and low-dose categories. Patients on high doses, meaning 1,000 micrograms or more daily, showed a hazard ratio of about 3.99 for developing IPF relative to non-users. By comparison, typical doses carried no apparent added risk.

The connection stood out most in those with chronic airway conditions like COPD or asthma. Younger patients, the analysis suggested, faced somewhat less danger than their older counterparts.

The results appeared in May in BMJ Open Respiratory Research, published by the British Medical Association.
