Prediction Model for an Unfavorable Course of Dizziness in Older Adults
| Predictor | B | OR (95% CI) | P Value |
|---|---|---|---|
| Intercept | −6.385 | – | – |
| DHI-S score,a per point | 0.127 | 1.14 (1.07–1.21) | <.001 |
| Age, per year | 0.063 | 1.06 (1.00–1.13) | .04 |
| History of arrhythmiab | 0.661 | 1.94 (0.81–4.63) | .14 |
| Looking up as provoking factorb | 0.690 | 1.99 (0.92–4.32) | .08 |
B = regression coefficient; OR = odds ratio; DHI-S = screening version of Dizziness Handicap Inventory.
Note: Adjusted model on internal validation, linear predictor = −5.687 + (0.115 × DHI-S) + (0.056 × age) + (0.597 × history of arrhythmia) + (0.623 × looking up as provoking factor).
↵a Score ranges from 0 to 40, with higher scores indicating more severe dizziness-related impairment.
↵b Yes = 1, no = 0.
