| Risk factors | Effect |
|---|---|
| Patient factors | |
| Age4 | Tear rates |
| <50 years | 5% |
| 50–59 years | 10% |
| 60–69 years | 15% |
| 70–79 years | 25% |
| >80 years | 34% |
| BMD14 | Relative risk |
| Normal (T-score > −1) | 1 |
| Osteopaenia (−1 > T-score > −2.5) | 4.38 |
| Osteoporosis (−2.5 > T-score) | 7.25 |
| Hyperlipidaemia (HL)15 | Relative risk |
| Normal lipid levels | 1 |
| HL | 6.5 |
| Critical shoulder angle (CSA)21>38° | Odds ratio 14.8 |
