Fig. 3From: Pressure pain threshold and temporal summation in adults with episodic and persistent low back pain trajectories: a secondary analysis at baseline and after lumbar manipulation or shamAdjusted mean change and 95% confidence intervals for pressure pain threshold and temporal summation after lumbar manual therapy intervention, by low back pain trajectory. * p < .05 for between-group differences over time (time by trajectory interaction).
