Transtympanic Electrocochleography for the Diagnosis of Ménière's Disease

Table 5

Conditions given for the calculation of four types of intermethod reliability (formula: reliability = (a/b) × 100).

Reliability	Conditions
Total	a = the smaller frequency of “positive” identification by one test
	b = the larger frequency of “positive” identification by the other test
Point by point	a = the number of cases with the same identification from both tests
	b = the total number of cases
Occurrence	a = the number of cases who tested “positive” in both tests
	b = the number of cases who tested “positive” at least in one test
Nonoccurrence	a = the number of cases who tested “negative” in both tests
	b = the number of cases who tested “negative” at least in one test
