Scatter Plot and Regression Line Between Flow-Mediated Dilation and Albuminuria in Sickle Cell Anemia: Urine albumin-creatinine ratio is significantly correlated with FMD (ρ = -0.45; 95% CI: -0.72 –-0.04, p = 0.031).
Fig 2.
Distribution of Flow-Mediated Dilation by Albuminuria Categories: FMD is lowest in patients with severely increased albuminuria compared with those with moderately increased and normal albuminuria, although the difference is not statistically significant (p = 0.16).

Scatter Plot and Regression Line Between Spot Urine Albumin-Creatinine Ratio and 24-Hour Urine Protein: Urine albumin-creatinine ratio is strongly correlated with total urinary protein assessed by 24-hour urine collection (ρ = 0.90; 95% confidence interval [CI]: 0.75–0.95, p < 0.0001).

Scatter Plot and Regression Line Between Spot Urine Albumin-Creatinine Ratio and Urine Aliquot for Albumin-Creatinine Ratio: Urine albumin-creatinine ratio assessed by spot albumin-creatinine ratio is strongly correlated with urine aliquots for albumin-creatinine ratio obtained from the 24-hour urine collection (ρ = 0.97; 95% CI: 0.92–0.99, p < 0.0001).
