Table 1. Characteristics of patients with a diagnostic biopsy.
| IPFnormal | IPFshort | TERT | |
|---|---|---|---|
| N | 17 | 15 | 17 |
| Male/Female | 16/1 | 13/2 | 14/3 |
| Mean Age at diagnosis (SD) | 61.2 (9.1) | 58.8 (10) | 58.7 (9.8) |
| Mean FVC%pred (SD) | 67.9 (23.7) | 73 (19.8) | 81 (15.6) |
| Mean DLCO%pred (SD) | 47.9 (20.3) | 44.9 (11.1) | 43.6 (6.2) |
| Smoking status (CS:FS:NS:U) | 0:11:5:1 | 2:10:1:2 | 0:14:3:0 |
| Pack years (SD) | 16.4 (15.6) | 23.9 (22.5) | 18 (15.5) |
IPF = Idiopathic Pulmonary Fibrosis; FVC = Forced Vital Capacity; DLCO = Diffusing Capacity of the Lungs for Carbon Monoxide. Pred = Predicted; IPFshort = lung telomere length in the same range as TERT patients: < 0.857; IPFnormal = lung telomere length above the range of TERT patients: > 0.857; CS = Current Smoker; FS = Former Smoker; NS = Never Smoker; U = Unknown.
No significant differences were present between patient groups (Kruskal-Wallis multiple comparison tests).
