Prediction Accuracy for FACE DROPS

FACE DROPS score	Prediction accuracy for BP	Prediction accuracy for LDFP
≤4	93.5%
5–6		71.4%
≥7		96.7%

Abbreviations: BP = Bell palsy; LDFP = Lyme disease–associated facial palsy.

For scores from −1 to 4, the tool is predictive of BP while for scores of 5 or more, the tool is predictive of LDFP.

The tool is most strongly predictive of LDFP with scores ≥7.
