Ordinal logistic regression of pain duration against Factor 1 (axial compression) and Factor 2 (soft tissue strain) with pain defined in three categories as <1 months, ≥1 months <3 months and ≥3 months (n = 333)

Predictor	OR	L95%CI	U95%CI	P-value
Factor 1: “Axial compression”	0.61	0.44	0.84	0.003
Factor 2: “Soft tissue strain”	1.30	0.59	2.86	0.521

OR – odds ratio, L95% CI – lower 95% confidence interval; U95% CI – upper 95% confidence interval
