Comparison of speech intelligence between personal sound amplification products (PSAPs) and conventional hearing aids. (A) The pooled result showed nonsignificant difference (SMD, 0.14; 95% CI, -0.19 to 0.47; P = .41; I2=65%). (B) After excluding the patients with moderately severe hearing loss in Cho et al., the result remained nonsignificant (SMD, 0; 95% CI, -0.23 to 0.23; P = .98; I2=24%). IV indicates the inverse variance method; SW indicates that the analysis adopted the Sound World Solutions CS50+ PSAP used in Brody et al.; MHL indicates mild hearing loss; MDHL indicates moderate hearing loss; MSHL indicates moderately severe hearing loss; PHA indicates premium hearing aid used in Cho et al.
