For doctors, it is much more reliable to diagnose diseases based on physical examination results than medical experience, and doctors may therefore require some patients with mild or non-pathological symptoms to undergo unnecessary medical examinations. However, the number and number of physical examination items also increase. In order to avoid the possibility of misdiagnosis, some indicators abnormal caused by errors in physical examination equipment may cause doctors to make wrong judgments. Can it be derived from this text? ['Medical examinations are gaining more and more attention as a way of health care.', 'Not all diseases can be detected by physical examination.', 'For patients, the more medical examinations, the better.', "Doctors' diagnosis based on experience is more scientific than the results of physical examination."]
