Results of the statistical analysis (marginal effects) of the time of informal care of patients with SMA.
| Informal Caregiving Time a (All Time of Care, Main Caregiver Plus Other Caregivers) | |||
| High Burden of Care (more than 10 h per day) | Intermediate Burden of Care (between 5 and 10 h per day) | Low Burden of Care (less than 5 h per day) | |
| dy/dx (Standard Error) | dy/dx (Standard Error) | dy/dx (Standard Error) | |
| Type of SMA (reference category = type III) | |||
| Type I | 0.36 * (0.17) | −0.05 (0.04) | −0.31 * (0.15) |
| Type II | 0.30 ** (0.10) | −0.04 (0.04) | −0.26 ** (0.08) |
| n | 64 | ||
| LR chi2 | 35.9 | ||
| Pseudo R2 | 0.26 | ||
| Informal caregiving time a (main caregiver’s time) | |||

| Type of SMA (reference category = type III) | |||
| Type I | 0.39 * (0.20) | −0.05 (0.05) | −0.34 * (0.17) |

* p < 0.05 ** p < 0.01. Note: regression models include sex, age, country, marital and job status of caregivers and whether the patient with SMA is receiving social services due to the illness as control variables. a These values represent the marginal effects obtained using ordered probit models.
