*4.2.2 Correlates of spot urine and daily urine creatinine excretion in non-HIV subjects*

Spot urine creatinine correlated significantly with body mass index (r = 0.225, p = 0.009), spot urine protein (r = 0.292, p = 0.001), spot urine osmolality (r = 0.223, p = 0.009), 24-hour urine protein (r = −0.187, p = 0.030), 24-hour urine creatinine (r = −0.178, p = 0.038), serum creatinine (r = −0.212,

p = 0.013), serum cholesterol (r = 0.246, p = 0.004), and serum low-density lipoprotein cholesterol (r = 0.282, p = 0.001). Factors that significantly correlated with 24-hour urine creatinine were 24-hour urine volume (r = 0.213, p = 0.013), serum creatinine (r = 0.741, p < 0.001), and spot urine creatinine (r = −0.178, p < 0.001). Spot urine protein and 24-hour urine protein predicted spot urine creatinine, whereas only serum creatinine predicted 24-hour urine creatinine.
