Fisher test using α=0,05, CI95% and power 80% between history of alergy/ARI with hearing loss type p= 1,00 (not significant), blood glucose index with hearing loss type p= 0,40 (not significant), history of alergy/ARI with hearing loss degree p= 0,49 (not significant), blood glucose index with hearing loss degree p= 0,44 (not significant).
