Decide to try Size Determination
A sample size calculation was conducted for logistic regression analysis (categorical variable). 22 This formula was first and . An explanation of the formula follows: n = the sample size in the first formula; nm = the absolute sample size; Z1-?/2 = the statistic corresponding to level of confidence (1.96); p1 = the event rates at proportion of lumbar instability absent; p2 = the event rates at proportion of lumbar instability present; p= the average value of p1 and p2; and B https://datingmentor.org/escort/mobile/ = the proportion of participants with lumbar instability present among all participants–this value was taken from the Puntumetakul et al study. 20 The total sample size required was 1678 participants, anticipating a 5% loss of response rate. The current study therefore required 1762 participants.
