TY - T1的特发性肺纤维化:another step in understanding the burden of this disease JF - European Respiratory Journal JO - Eur Respir J SP - 26 LP - 28 DO - 10.1183/13993003.00907-2016 VL - 48 IS - 1 AU - Hutchinson, John Y1 - 2016/07/01 UR - //www.qdcxjkg.com/content/48/1/26.abstract N2 - The past 25 years have seen a steady increase in the number of studies examining the incidence of idiopathic pulmonary fibrosis (IPF) worldwide [1, 2]. In general, early studies tended to involve clinicians collating cases from their local area [3, 4] or asking interested colleagues to contribute to registries [5, 6], whereas later studies have made use of large databases collected for clinical care or administrative reasons [7–10]. These later studies boasted far greater numbers, though with some concern about the validity of the cases, the reliability of clinical coding and generalisability to the wider population. A recent systematic review estimated the incidence of IPF to be 3–9 cases per 100 000 in Europe and North America, although this included a heterogenous mix of studies with different case definitions and populations, and several less reliable estimates had to be excluded [2]. Therefore, identifying the true incidence of IPF remains a challenge [11].Idiopathic pulmonary fibrosis: good-quality Canadian study with high incidence adds to the epidemiological jigsaw http://ow.ly/gArO300hdSxWith thanks to Richard Hubbard (University of Nottingham, Nottingham, UK) for his comments on this work.
