Data were pooled using random\u2010effects with three models. The effect of demographic, clinical, and measurement\u2010related parameters was specifically analyzed.

However, study populations (general population, patients with a cochlear implant, and patients with congenital sensorineural hearing loss [CSNHL]) were found to affect the outcomes. Compared to the other populations, patients with CSNHL had shorter cochleae.
