Given that an estimated 1 in 7 US adults has CKD, in conjunction with CKD's significant quality-of-life burden (eg, renal replacement therapy) on patients, we assessed the relationship between psoriasis and CKD in a nationally representative sample of US adults. 4 Centers for Disease Control and PreventionChronic kidney disease in the United States. https://www.cdc.gov/kidneydisease/publications-resources/ckd-national-facts.htmlDate: 2021 Date accessed: October 12, 2022 Google Scholar
