In 1967-68 an age-stratified random sample of 1069 current workers in Quebec asbestos mines and mills was surveyed. Questions concerning rheumatic complaints were included in a modified MRC questionnaire used at that time, and on this basis a rheumatic severity gradient was devised. No relationship could be detected between rheumatic complaints and pulmonary radiologic response to chrysotile dust exposure, despite implications in the literature that such a relationship might exist.
1967年至1968年,对魁北克石棉矿和工厂的1069名在职工人进行了分层随机抽样调查。当时使用的经过修改的医学研究委员会(MRC)问卷中包含了有关风湿性疾病主诉的问题,并据此设计了一个风湿严重程度梯度。尽管文献中暗示可能存在这种关系,但未发现风湿性疾病主诉与温石棉粉尘暴露的肺部放射学反应之间存在关联。
