Factors associated with requiring more help by researchers completing the MDP and D-12
| OR (95% CI) | ||||
| MDP | D-12 | |||
| Help required to complete the instrument | Univariate | Multivariate | Univariate | Multivariate |
| Age (per 10 years) | 3.05 (1.04 to 8.94) | 3.25 (1.10 to 9.63) | 3.88 (1.09 to 13.84) | 3.83 (1.06 to 13.78) |
| Gender (women vs men) | 1.56 (0.35 to 6.84) | 2.24 (0.47 to 10.80) | 0.60 (0.14 to 2.62) | 0.85 (0.18 to 4.05) |
Help required by researchers for patients (n=50) to complete MDP and D-12 over telephone. Help required was recoded into 0=‘none’ or ‘a little’; 1=‘moderate’ or ‘a lot’. ORs were analysed using logistic regression for age and gender separately (univariate) and concurrently (multivariate).
