Pomeroy VM, Rowe P, Clark A, Walker A, Kerrt A, Chandler E, Barber M, Baron J-C. A randomized controlled evaluation of the efficacy of an ankle-foot cast on walking recovery early after stroke: SWIFT Cast Trial. Neurorehabil Neural Repair. 2016;30:40-48.

During secondary analysis of the SWIFT Cast Trial data the authors identified an error in the values reported in the above paper for peak angular velocity of the knee (Peak knee AV). The error is that the reported values for peak knee AV are misreported by a factor of 7. The data concerned is in tables 1, 2 and 5. The corrected values, with effect sizes and P values where appropriate, are present below:

Table 1.

Participant Characteristics at Baseline.

	CPT (n = 54)	Swift Cast (n = 51)
Peak knee velocity, nonparetic (degrees/s)	38.91 (71.75)	32.34 (65.88)
Peak knee velocity, paretic (degrees/s)	31.74 (58.76)	26.67 (57.63)

Table 4.

Secondary Measures at Outcome.

	CPT (n = 45)	Swift Cast (n = 46)	Effect Size (95% CI)	P Value
Peak knee velocity, nonparetic (degrees/s)	172.05 (254.77)	194.24 (382.36)	29.54 (–91.84,184.88)	0.648
Peak knee velocity, paretic (degrees/s)	153.48 (316.45)	137.22 (269.79)	–9.03 (137.27, 103.67)	0.884

Table 5.

Secondary Measures at Follow-up.

	CPT, Mean (SD), n = 42	Swift Cast, Mean (SD), n = 36	Effect Size (95% CI)	P Value
Peak knee velocity, nonparetic (degrees/s)	191.00 (291.35)	228.71 (363.23)	35.14 (–134.05,195.79)	0.674
Peak knee velocity, paretic (degrees/s)	163.32 (240.37)	169.37 (319.34)	7.42 (–131.11,142.66)	0.915

Please note that the P values have changed but the difference between the two groups remain non-significant. Therefore, the interpretation of the data and conclusions presented in the published paper have not changed.
