|---|---|---|---|---|---|
| Risk in group 1 | 0.029 | 0.0205 | 0.0409 | wilson | |
| Risk in group 2 | 0.0311 | 0.023 | 0.0419 | wilson | |
| Risk difference, group 1 minus group 2 | -0.00206 | -0.0158 | 0.0123 | newcombe hybrid score | |
| Risk ratio, group 1 over group 2 | 0.934 | 0.59 | 1.48 | log | |
| Odds ratio, group 1 over group 2 | 0.932 | 0.58 | 1.5 | log | |
| Number needed to treat, for one fewer participant with the outcome on Static Frequency than on Dynamic Frequency | 485 | from the risk difference interval | the interval includes no difference |
