Figure 1 Patient flow chart. ¹The cohort consists of all patients undergoing spinal instrumentation surgery between January 2006 and December 2008 at British Columbia Children’s Hospital (Vancouver, Canada); ²Controls were matched for sex, age, and underlying diagnosis (idiopathic vs non-idiopathic scoliosis).

Figure 2 Acute kidney injury incidence according to intra-operative fluid management and nephrotoxin exposure. A: Acute kidney injury (AKI) incidence according to fluid tertile: Fluid tertile 1 (70%) vs fluid tertile 2 (50%) vs fluid tertile 3 (29%) (P = 0.02); B: AKI incidence according to fluid tertile and nephrotoxin exposure: Fluid tertile 1 with nephrotoxin exposure (75%) vs fluid tertile 3 with no nephrotoxin exposure (10%) (P = 0.04).
