Table 1. Clinical and demographic characteristics of study participants.

Mean values for each clinical and demographic characteristic, with standard deviation (SD) in parentheses. n= 17 non-Dantu, 16 Dantu heterozygous and 13 Dantu homozygous individuals. Statistical comparison across genotypes was performed using the Kruskal-Wallis test, while pairwise comparisons between groups performed using Dunn’s test. P adj* - adjusted for age, sex and multiple comparisons with Benjamini-Hochberg FDR adjustment. *p < 0.05.
