¸ñÀû: To compare the electrophysiologic hearing thresholds provided by Click-evoked Auditory
Brainstem Response (c-ABR) and Auditory Steady-State Response (ASSR) across various
frequencies in pediatric population. ¹æ¹ý:A systematic review was conducted using Google Scholar, ProQuest, PubMed, and
ScienceDirect, focusing on correlation coefficients between c-ABR and ASSR thresholds across
various frequencies. The review included 22 observational studies. Meta-analyses were
conducted using random effects models, with subgroup analyses based on various factors. °á°ú:The overall correlations between c-ABR and ASSR thresholds were strong and significant
across different ASSR frequencies. The random effects model indicated a correlation
coefficient (COR) of 0.73 (95% CI: 0.21 to 0.93) at 1 kHz (4 studies), 0.83 (95% CI: 0.69 to
0.91) at 2 kHz (9 studies), 0.82 (95% CI: 0.71 to 0.89) at 4 kHz (9 studies), 0.84 (95% CI:
0.68 to 0.93) for 1-4 kHz (10 studies), and 0.84 (95% CI: 0.72 to 0.92) for 2-4 kHz (15
studies). Substantial heterogeneity was observed (I©÷: 86.2% - 97.1%). The high fail-safe N
values suggested robustness against publication bias. Subgroup analyses revealed
significant differences based on ABR instruments, while other factors such as countries,
sample sizes, and publication dates did not show significant differences. ASSR stimuli of
modulated tones provided stronger correlations with c-ABR thresholds compared to chirp
stimuli. Despite this, ASSR notably lacks the ability to recognize Auditory Neuropathy
Spectrum Disorder. °á·Ð:This systematic review and meta-analysis demonstrates that ASSR provides reliable
frequency-specific information that correlates well with c-ABR thresholds, making it valuable
for pediatric audiology. ASSRs limitation prompts clinicians to combine it with other
audiological tests. The findings are particularly relevant for resource-limited settings, where
ASSR can offer a practical solution for detailed hearing assessments. Despite high
heterogeneity, the results are robust and highlight the need for further research to explore
contributing factors. |
