For example, patients with high risk of renal failure or patients treated with insulin ± oral medication were expected to have 20% higher ‘hazard’ of a normal recovery with VRT compared to usual care (HR = 1.20, 95% CI 0.95–1.51 and HR = 1.20, 95% CI 0.99–1.46 respectively). The gene discussed is INS; the disease is kidney failure.
