Gd. Meyer et Db. Wirth, AN EVALUATION OF THE UNITED-STATES-AIR-FORCES DETAILED FOLLOW-UP AUDIOMETRIC EXAMINATION PROGRAM, Military medicine, 158(9), 1993, pp. 603-605
The authors used information on individuals demonstrating permanent th
reshold shifts contained in the United States Air Force Hearing Conser
vation Data Registry to evaluate the effectiveness of detailed follow-
up audiometric examinations as part of the USAF Hearing Conservation P
rogram. Analysis yielded a relative risk of 1.00 with a 95% confidence
interval of 0.97-1.03, which indicates a high probability that the tr
ue effect of these audiograms on the results of the next annual exam i
s minuscule, if not zero.
