TABLE 4.

Uni- and multivariate models for progression at 1 year and scoring of significant variables.

Variable	Univariate		Multivariate		Score points
	OR (95% CI)	P-value	OR (95% CI)	P-value
Age ≥70 vs. <70 years	2.29 (0.98–5.35)	0.055			–
Sex (female vs. male)	0.68 (0.29–1.61)	0.191			–
Traction bronchiectasis/honeycombing 1–4 vs. 0	3.39 (0.69–16.5)	0.132	3.38 (0.67–17.3)	0.142	1
Traction bronchiectasis/honeycombing 5–6 vs. 0	9.00 (1.57–51.46)	0.014	8.54 (1.43–51.2)	0.019	2
Reticular lung abnormalities 5–6 vs. 0–4	2.48 (0.97–6.37)	0.059			–
Blood monocyte count ≥0.65 vs. <0.65 G/L	3.28 (1.36–7.89)	0.008	3.16 (1.27–7.88)	0.014	1
Blood lymphocyte count ≥1.6 vs. <1.6 G/L	1.02 (0.44–2.34)	0.971			–
Forced vital capacity (L)	0.98 (0.65–1.49)	0.933			–
Diffusion capacity for carbon monoxide [mmol/(min × kPa)]	0.94 (0.72–1.22)	0.632			–

Reticular lung abnormalities score of 0 was only present in one patient, thus the scores were merged to 0–4. OR, odds ratio; CI, confidence interval. Bold values indicate statistically significant variables.
