Methods
  • Study design: parallel RCT

  • Study duration: recruitment February 2008 to August 2010

  • Duration of follow‐up: 12 months

Participants
  • Setting: multicentre

  • Country: Japan

  • Patients aged 18 to 65 years undergoing primary kidney transplantation

  • Number: treatment group (61); control group (61)

  • Mean age ± SD (years): treatment group (42.5 ± 14.13); control group (38.6 ± 11.36)

  • Sex (M/F): treatment group (46/15); control group (37/24)

  • Exclusion criteria: no evidence of graft function within 24 hours of transplantation; cold ischaemia time > 24 h; donor age > 65 years; patients of multiorgan, ABO‐incompatible, positive T‐cell cross‐match or HLA identical living‐related‐donor transplants; PRA > 20%

Interventions Treatment group
  • CsA trough levels: 100 to 200 ng/mL (months 0 to 2), 75 to 150 ng/mL (months 2 and 3), 50 to 100 ng/mL (months 4 and 5), 25 to 50 ng/mL thereafter

  • EVL trough levels: 3 to 8 ng/mL (from day 5)


Control group
  • CsA trough levels: 200 to 300 ng/mL (months 0 to 2), 100 to 250 ng/mL thereafter

  • MMF: 2 g/d


Both groups
  • Basiliximab induction

  • PRED: as per local protocol, minimum dose of 5 mg/d at 12 months

Outcomes
  • Efficacy failure: defined as the composite of treated BPAR, graft loss, death or loss to follow‐up at 12 months

  • Composite of graft loss, death or long‐term follow‐up at 12 months

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Independent validated system that automated the random assignment of treatment arms
Allocation concealment (selection bias) Unclear risk Insufficient information to permit judgement
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Open‐label study
Blinding of outcome assessment (detection bias) 
 All outcomes Unclear risk Most outcomes were objective, however there was no blinding of assessment
Incomplete outcome data (attrition bias) 
 All outcomes Low risk ITT analysis all patients analysed
Selective reporting (reporting bias) Low risk Prespecified outcomes were reported
Other bias High risk Funded by Novartis who also helped in manuscript development
