2.6 Subgroup analysis
The article performed the following subgroup analyses using treatment
regimen as a variable: medication alone, medication combined with
hyperbaric chamber therapy, and medication combined with intradural
steroid injection. Changes in recovery rates and changes in ORs in
people with SSHL suffering or free from vertigo were compared across
treatment regimens. Unfortunately, we tried to quantify the
heterogeneity of the study population to determine the relationships
between hearing age, degree of hearing loss, hearing graph, treatment
regimen, and level of hearing benefit; however, we had to abandon these
subgroups because of the paucity of studies that could provide relevant
information.
