The crystals aspect.

Serum uric acid was measured by oxidization with the specific enzyme uricase to form allantoin and H2O2 (Hitachi Model 737 Multichannel Analyzer; Boehringer Mannheim Diagnostics, Indianapolis, IN), as detailed elsewhere ( 13 ).

Your body size directory (BMI) is actually computed by the breaking up the extra weight into the kilograms by the square of one’s top in meters.

Analytical studies.

Most of the analytical analyses was basically performed using questionnaire instructions away from Stata application (age.g., SVYMean and you may SVYReg) to provide sample loads also to to switch getting clusters and you may strata of the cutting-edge attempt framework (version eight; Stata, University Channel, TX).
