Antemortem diagnosis of asbestosis by screening chest radiograph correlated with postmortem histologic features of asbestosis: a study of 273 cases

Table 1 Comparison of the antemortem chest radiograph diagnosed group vs. the group diagnosed by history alone

	Positive Chest Radiograph			Control Group			P-value
	Yes	No	% Yes	Yes	No	% Yes
Pleural Plaques	148	94	61.1	11	20	35.4	0.0109
Fibrosis	157	85	64.8	14	17	45.1	0.0472
Tissue Ferruginous Bodies	100	142	41.3	4	27	12.9	0.0016
Digestion Ferruginous Bodies*	169	55	75.5	13	15	46.4	0.0028
Histologically proven	89	153	36.8	3	28	9.7	0.0021

* It should be noted that the total number of cases listed for ferruginous bodies tissue digestion does not equal 273 because there
were cases in both the study group and the control group in which tissue digestion was not performed or documented.
