“…Spearman’s correlation coefficients facilitated the analysis of correlations between the HH or the HH/HT ratio, the carpal tunnel’s CSA, postoperative nerve conduction velocity, VAS, Quick DASH, and the BCTQ FSS, and SSS. The correlation strength was categorized as follows 15 : very strong (absolute value, ≥0.8), strong (absolute value, 0.60–0.79), moderate (absolute value, 0.40–0.59), weak (absolute value, 0.20–0.39), and very weak (absolute value, 0.00–0.19). The incidence of complications was compared between cases with and without a hypoplastic hook using Fisher’s exact test.…”
