Exposure Assessment of the Study Population (N = 83)^*

Exposed to beryllium	n	Age (years)		Working years (years)		Positive BeLPT^† (n = 15, 18.1%) %
Exposed to beryllium	n	M	SD	M	SD	Positive BeLPT^† (n = 15, 18.1%) %
Yes	61	43	11.9	20.4	10.6	25%^‡
No	22	36	9	14.2	10.1	4.8%^‡
		p = .015^§		p = .024^§		OR: 3.2 CI: 0.97–10.6 p = .06

Note. BeLPT = beryllium lymphocyte proliferation tests; OR= odds ratio; CI = confidence interval.

Self-reported on a questionnaire.

^†

Positive BeLPT: 2 or more concentration above the SI in BeLPT test (CBD or BeS).

^‡

Percentage of positive BeLPT (4.8% represent 1 worker that was unaware of his exposure).

^§

t test analysis: p = .015 for age and p = .024 for cumulative years of exposure.

Chi-square analysis.
