Future study participation in unaffected individuals and in schizophrenia.
| Unaffected controls | Schizophrenia | Model 1a | Model 2b | |
|---|---|---|---|---|
| Willing to participate in future studies | Frequency (%) | Frequency (%) | Odds-ratio (95% confidence interval) | Odds-ratio (95% confidence interval) |
| Yes | 4129 (93.6) | 2230 (82.7) | Ref. | Ref. |
| No | 33 (0.75) | 121 (4.5) | 6.8 (4.6–10.0)c | 7.9 (5.3–11.7) c |
| Donť know | 250 (5.7) | 346 (12.8) | 2.6 (2.2–3.0) c | 2.9 (2.4–3.4) c |
The analysis is based on 4412 unaffected and 2697 individuals with schizophrenia. Not included missing responses in unaffected individuals (N=54) and schizophrenia (N=70). Multinomial logistic regression was used for analysis with an affirmative answer (Yes) as reference. An odds-ratio greater than one indicate that individuals with schizophrenia are more likely to answer, “No” or “Don’t know” to the question of willingness to participate.
a
No adjustments.
b
Adjusted for sex and age at participation.
c
P-value < 0.0001.
