¹Includes a 7.5 mg/kg treatment, a 5 to 7.5 mg/kg step-up program, and a 5 to 10 mg/kg step-up program.

²Includes both a 7.5 mg/kg treatment and a 5 to 10 mg/kg step-up program.

³Weighted average duration of feeding.

⁴Weighted average treatment mortality was calculated using only studies where direct comparisons where available, with each study weighted by sample size.
