This meta-analysis investigates the diagnostic accuracy of using the Gaps-in-Noise (GIN) test to discriminate patients with central auditory nervous system damage within the broader context of central auditory processing disorder assessment.

Meta-analysis of eight studies investigating the diagnostic accuracy of gaps-in-noise (GIN) testing to discriminate between individuals with a neurological difference (e.g., epilepsy, stroke, blast-injury) of the central auditory nervous system (CANS) and control patients calculated an overall sensitivity rate of 72%, a specificity rate of 93%, a high positive likelihood ratio, a low negative likelihood ratio, and relatively large diagnostic odds ratio. These findings indicate that performance on GIN testing can suggest the presence of a neurological lesion or CANS dysfunction in individuals. "The good accuracy rates in identifying individuals with neuroauditory lesions, along with the overall consistent performance of normal controls, showcase the GIN test as a powerful clinical tool that can be used to investigate temporal resolution dysfunction and be used reliably across languages and cultures" (p. 10).
