How did the testimony of two witnesses in a medical malpractice case affect their own opinions?

Prior to testifying, the doctor witnesses had apparently read and considered medical reports containing recitations of fact. However, with only minor and unimportant exceptions these recitations were supported by other evidence in the record. The reports also contained the opinions of two doctors who did not testify. But from the whole testimony of the doctor witnesses we are satisfied that their own opinions were not materially affected by their awareness of the opinions of the non-testifying doctors. Cf. Clifton v. Mangum, 366 F.2d 250, 253 (10th Cir. 1966).
