Data presented in the table are unadjusted. Total intervention groups are in bold. The intracluster correlation coefficient (ICC) is 0.0053. For the test of equal LBP rate across intervention groups, comparing TEP Yes vs No, and comparing PSEP Yes vs No, the Chi-Square values equal to 6.99, 0.54, and 5.56; with corresponding P-values of 0.0722, 0.4641 and 0.0183, respectively. Adjusting for ICC, the Chi-square values reduce to 6.35, 0.49, and 5.05; with corresponding P-values of 0.0957, 0.482 and 0.0246, respectively
