Ojelabi et al. 201520 | • Adults with SCD • Nigeria |
• SF-6D | • SCD in general | • Utility for SCD in general: 0.65 (SD 0.12) • Utility for SCD in general for males: 0.66 (SD 0.11) • Utility for SCD in general for females: 0.64 (SD 0.12) • Utility decrement due to one year older: 0.023 (SE 0.014) |
QALY-based cost-effectiveness analysis | ||||
Bradt et al., 202023 | • SCD patients • U.S. |

Cherry et al. 201224 | • SCD patients • U.K. |
• Based on literature | • SCD with normal TCD velocity | • Utility for SCD with blood velocity of < 200 cm/second: 0.22 (per three months) |
QALY-based simulation modeling study | ||||
Lubeck et al. 201927 | • SCD patients • U.S. |
