Table 4.
Risk of chronic kidney disease (CKD) attributable to severe psoriasis by age*
| Age range (years) | Risk of chronic kidney disease (95% CI) | |
|---|---|---|
| Attributable risk (per 1000 person years) | Excess risk (case per No of patients per year) | |
| 20-30 | 1.17 (0.87 to 5.30) | 1/855 (646 to 1153) |
| 30-40 | 2.89 (2.26 to 3.64) | 1/346 (275 to 443) |
| 40-50 | 7.48 (6.15 to 8.97) | 1/134 (112 to 163) |
| 50-60 | 16.21 (13.84 to 18.80) | 1/62 (54 to 73) |
| 60-70 | 27.93 (23.11 to 33.15) | 1/36 (31 to 44) |
| 70-80 | 31.44 (20.89 to 43.23) | 1/32 (24 to 48) |
*Attributable and excess risks calculated at median age within each age group by using adjusted hazard ratios for CKD in patients with severe psoriasis and incidence of CKD in unexposed patients.
