Table 2. YES a.c. – all subjects with audiogram change; NO a.c. – subjects without audiogram change; 10 dB – subjects with 10 dB audiogram reduction; 5 dB – subjects with 5 dB audiogram reduction; audiometry and nasal secretion samples were performed at three time points: I – 24 hours before, II – immediately after, and III – 24 hours after gunshot exposure (a regular shooting exercise with the CZ 99 pistol using earplugs); n=105 (military cadets of both sexes, healthy, all Caucasian, aged 19–25 years). Cytokine levels are expressed in pg/mL and given as mean ± standard deviation. Levels of statistical significance: * – p0.05; ** – p0.01.
