— Quantitative comparison of peritoneal fibrosis and vascular sclerosis and their correlation with peritoneal dialysis (PD) duration. (a) Thickness of the submesothelial compact zone (SMC). (b) Ratio of lumen-to-vessel (L/V) diameter. (c) Correlation between SMC and PD duration. (d) Correlation between L/V ratio and PD duration. The SMC was thinner and the L/V ratio was greater, significantly so, in the group on neutral dialysate compared with the group on acidic dialysate. The SMC thickness and L/V ratio were significantly correlated with PD duration in the group on acidic dialysate; no significant correlation was found in the group on neutral dialysate.
