Laslett's "Clinical Prediction Rule 5" for predicting positive screening medial branch block
Criteria	Points	Present
Age > 50	1
Symptoms best walking	1
Symptoms best sitting	1
Onset pain is paraspinal	1
Positive extension/rotation test	1
Probability	Negative (0)

3 or more criteria has a positive likelihood ratio of 9.7 (5.0, 18.8) and negative likelihood ratio of 0.17 (0.05, 0.60) for positive initial screening medial branch block^[1]
