Correlation between serum lipids concentrations and clinical and laboratory data in patients with AD. The heatmap shows the correlation between serum lipids concentrations and clinical/laboratory data in patients with AD. Color red to blue indicates correlation coefficient (ρ). Correlations were analyzed by Spearman’s correlation test. The P-values for multiple comparisons were adjusted using Benjamini‒Hochberg procedure. The ρ values and P-values are shown in Tables 2 and 3. AD, atopic dermatitis; BMI, body mass index; BSA, body surface area; Cer, ceramide; EASI, eczema area and severity index; LPC, lysophosphatidylcholine; LPE, lysophosphatidylethanolamine; PAF, platelet-activating factor; PC, phosphatidylcholine; SCORAD, severity scoring of atopic dermatitis; SM, sphingomyelin; Sph, sphingosine; TARC, thymus and activation-regulated chemokine.
