Abbreviations. TP, true positives; FN, false negatives; FP, false positives; TN, true negatives; CI, confidence interval; PPV, positive predictive value; NPV, negative predictive value; LR+, positive likelihood ratio; LR-, negative likelihood ratio; OR, odds ratio.

Note: Cell counts do not total 153 in some cases due to missing data.
-
aAny combination of the following positive tests: onset of pain due to repetitive activity; no pain referral below elbow; ACJ thickened or swollen; typical symptoms are not provoked during PROM GHJ abduction or PROM external rotation (90° abduction).
- † Invalid calculation (no participants reported five positive clinical tests).
- ** P≤0.01; *** P≤0.001.
