However, SUA levels largely depend on renal clearance function. This study aims to investigate the correlation between serum uric acid to creatinine (SUA\/SCr) ratio and time in range (TIR) in patients with type 2 diabetes mellitus (T2DM).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>TIR was assessed using continuous glucose monitoring (CGM) systems in 514 hospitalized patients with T2DM. Biochemical parameters, including blood glucose, liver and renal function markers, and blood lipids, were measured. SUA\/SCr was calculated, and its association with TIR was analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One\u2010way ANOVA revealed significantly higher TIR levels in the SUA\/SCrQ3 group compared to the Q1 group (72.90% [60.08%, 83.38%] vs. 80.20% [70.25%, 89.65%], <jats:italic>p<\/jats:italic>\u2009=\u20090.0084). Smooth curve fitting and threshold effect analyses demonstrated an inverted <jats:italic>U<\/jats:italic>\u2010shaped association between SUA\/SCr and TIR after multivariable adjustment. Before the inflection point (SUA\/SCr\u2009=\u20096.471), a positive correlation was observed (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20091.402, <jats:italic>p<\/jats:italic>\u2009=\u20090.0379), indicating a 1.402% increase in TIR per 1\u2010unit increase in SUA\/SCr. Beyond the inflection point, a negative correlation emerged (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22124.406, <jats:italic>p<\/jats:italic>\u2009=\u20090.0043), corresponding to a 4.406% decrease in TIR per 1\u2010unit increase in SUA\/SCr. Trend tests confirmed the statistical significance of these bidirectional associations. Interaction analyses indicated that gender, BMI, GLP1RA\u2010therapy, SGLT2i\u2010therapy did not significantly modify the SUA\/SCr\u2010TIR association (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05 for all). However, age significantly modified this relationship (<jats:italic>P<\/jats:italic> for interaction\u2009=\u20090.0240). Subgroup analysis by age revealed a curvilinear association in participants aged\u2009&lt;\u200965 years, with no significant association below the inflection point (SUA\/SCr = 6.559; <jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.796, <jats:italic>p<\/jats:italic>\u2009=\u20090.2803) but a significant negative association above it (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22124.392, <jats:italic>p<\/jats:italic>\u2009=\u20090.0059).
