Table 4. Relative frequencies of fibred confocal fluorescence microscopy (FCFM) patterns by diagnostic group.
| FCFM patterns | Patients | ||
|---|---|---|---|
| Chronic fibrosing (n=16, %) | Other ILD (n=11, %) | Overall (n=27, %) | |
| Normal | 9 (56.2) | 9 (81.8) | 18 (66.7) |
| Non-specific | 13 (81.2) | 5 (45.5) | 18 (66.7) |
| Increased fibres | 10 (62.5) | 7 (63.6) | 17 (63.0) |
| Densely packed fibres | 11 (68.8) | 4 (36.4) | 15 (55.6) |
| Hypercellular | 3 (18.8) | 8 (72.7) | 11 (40.7)* |
| Thickened fibres | 5 (31.2) | 2 (18.2) | 7 (25.9) |
Binominal proportion test was used with normal approximation to calculate P value. *, P<0.05. ILD, interstitial lung disease.
