Summary

We aimed to assess the association between postoperative new-onset proteinuria, all-cause mortality, and decline in kidney function in Chinese people who underwent surgery. The exposure variable was the dipstick proteinuria values from the initial postoperative urinalysis within 30 days after surgery, categorized as negative, trace, 1+, and ≥2+. The primary outcome was 30-day mortality. The secondary outcomes included 1-year mortality and composite kidney outcome assessed using the postoperative estimated glomerular filtration rate.
