Burst: ... % i. * *. - \ We have finally finished compilation of the medical data on each of'the Pittsburgh Corning employees and the paperwork Involved la notifying them and reporting the summaries to their personal physicians. Pa afraid 1 didn't realize how much time this would take when 1 agreed to Hr. Wodka's request to repost on each nun. . To review the procedure I used In Issuing our findings: each employee will receive one of four basic torso letters (depending on his results) Informing him that we have completed our analysis and have sent a summary of the findings to his personal physician, to Dr. Grant, and to you. The personal physician is being sent, at toe same time, a carbon of the patient's letter, a data sheet on the patient accompanied by an explanation farm, and a cover letter the survey. Enclosed with this letter yon will also find a carbon f the patient's letter, the data shoot and the explanation form. Cr. Grant will receive the same. This project has been complicated by the fact that not all fiis workers signed both releases* There are five sea who consented to notifying you and Br.. Grant, but who had no personal physician. Am you will see in the enclosures, we recommended they see you to learn specific results of their study,- to addition. I'm enclosing one of the fbrm letters to the local doctors addressed to you with these men's names..

Four men did not sign any releases and are now being contacted individually. The total number of workers who received both your and our examinations came to fifty. We do not Intend contacting anyone who participated In nly one. Your roentgenograms will bo returned under separate cover dong with ths interpretation by our panel of radiologists on each film whether or not they were examined by os. Once again. I thank you for their use and apologize for die long delay la returning diem. On the technical side, yon will note that on the data sheet, we hove used year raw figures to calculate die FEVj% (FEVj/FVC ratio) which we felt was a helpful parameter in differentiating restrictive and obstructive ventilatory deflects.
