The Effect of Shear Force on Skin Viability in Patients with Type 2 Diabetes

Figure 4

(a) Correlation between baseline glucose concentration in blood (mmol/l) and cutaneous blood cell flux directly after shear combined with pressure loading (time point 0) in patients with type 2 DM (-0.5, 95% CI -0.8 to –0.01, ). Correlation was tested with the Spearman rank test. (b) Correlation between CNE score and cutaneous blood cell flux directly after shear combined with pressure loading (time point 0) in patients with a CNE score of ≥1 (0.2, 95% CI –0.4 to 0.7, ). Correlation was tested with the Spearman rank test. (c) Correlation between IL-1α concentration (pg/ml) and cutaneous blood cell flux (AU) directly after shear combined with pressure loading (time point 0) (0.2, 95% CI -0.2 to 0.5, ). Correlation was tested with Spearman rank test (). (d) Correlation between baseline glucose concentration in blood (mmol/l) and IL-1α concentration (pg/ml) directly after shear combined with pressure loading (time point 0) in patients with type 2 DM (-0.1, 95% CI -0.5 to 0.4, ). Correlation was tested with the Spearman rank test (). (e) Correlation between VALK score and IL-1α concentration (pg/ml) directly after shear combined with pressure loading (time point 0) (95% CI -0.6 to 0.5, ). Correlation was tested with the Spearman rank test (). Only participants with a VALK score of ≥1 were included in the analysis.
