In addition, there was an error on page 2. The following paragraph is updated as it was incorrectly formulated:

The original incorrect wording:

Here, n = 34 in each group, Z_1-α/2 = standardised level of significance = 95% = 1.96, Z_1-β = Power of test = 80% = 1.28, µ₁ = Mean in control group = 4.60, µ₂ = Mean in physiotherapy group = 5.40, δ₁² = standard deviation in control group = 0.84, δ₂² = standard deviation in physiotherapy group = 0.59. The primary outcome used to estimate sample size was vital capacity (VC) (Duymaz 2019). A difference of 0.5 in the standard deviation was regarded as a meaningful change (Hislop et al. 2014).

The revised and updated wording:

Here, n = 15 in each group, Z_1-α/2 = standardised level of significance = 95% = 1.96, Z_1-β = power of test = 80% = 1.28, µ₁ = mean in control group = 4.60, µ₂ = mean in physiotherapy group = 5.40, δ₁² = standard deviation in control group = 0.84, δ₂² = standard deviation in physiotherapy group = 0.59. The primary outcome used to estimate sample size was vital capacity (VC) (Duymaz 2019). A difference of 0.5 in the standard deviation was regarded as a meaningful change (Hislop et al. 2014).
