Non-referral group, n (%)Referral group, n (%)P value
CKD status
 CKD 3B856 (72.60)249 (69.75)
 CKD 4279 (23.66)96 (26.89)
 CKD 544 (3.73)12 (3.36)0.453
Albuminuria and proteinuriaa
 Normal to mildly increased 290 (28.29)97 (29.57)
 Moderately increased 402 (39.22)109 (33.23)
 Severely increased 333 (32.49)122 (26.8137.20)0.126
  • P value is taken from χ2 tests.aAlbuminuria and proteinuria data (albumin-to-creatinine ratio [ACR] or protein-to-creatinine ratio [PCR]) were available for 1353 patients, 1025 in the non-referral and 328 in the referral group. CKD = chronic kidney disease
