Association between obstructive sleep apnoea (OSA) risk determined by the STOP-BANG questionnaire (SBQ) and Epworth Sleepiness Scale (ESS) with the likelihood of having age-related macular degeneration (AMD) or reticular pseudodrusen (RPD) coexistent with AMD (n=337)
| Parameters | AMD | RPD coexistent with AMD | ||
| OR (95% CI) | P Value | OR (95% CI) | P Value | |
| OSA risk (SBQ+ESS; binary) | ||||
| Non-high risk (n=274) | Ref | 0.698 | Ref | 0.885 |
| High risk (n=63) | 1.13 (0.61 to 2.07) | 1.05 (0.53 to 2.11) | ||
| OSA risk (SBQ; ordinal) | ||||
| Low risk (n=169) | Ref | 0.519 | Ref | 0.551 |
| Intermediate risk (n=142) | 1.35 (0.79 to 2.31) | 1.36 (0.75 to 2.46) | ||
| High risk (n=26) | 1.39 (0.53 to 3.65) | 1.55 (0.49 to 4.93) | ||
| SBQ score (continuous) | ||||
| Per point increase | 1.09 (0.88 to 1.36) | 0.441 | 1.16 (0.90 to 1.51) | 0.252 |
| ESS score (continuous) | ||||
| Per point increase | 1.04 (0.96 to 1.12) | 0.353 | 1.02 (0.94 to 1.11) | 0.679 |
Evaluation of each parameter was performed adjusting for age, gender and smoking history.
