Figure 1

Major characteristics of SB- (hatched bars) vs. SF- (light bars) patients. U: fasting urine; B: fasting blood; FE: renal fractional excretion (conceived as indicator of the capacity of tubules to lose or reclaim UA); for other abbreviations see below and text. Note that negative DG (I IAP, CaOx) by definition mean urine undersaturation (synonymous solubility, i.e. no solid formation and dissolution of preformed solid (41)). +: sum of urinary UA precursor oxypurine (HX: hypoxanthinc; XA: xanthine) excretion rates; *: based on log10 data; n: number of patients.
