Assessment of the effect inferred by the participants: did the participants feel an effect by the interventions taken?
| Mean±SD effectiveness (0–10) | P value | |
| FSMP (n=69) | 4.22±1.485 | 0.02 |
| Vitamins and minerals (n=76) | 2.67±1.30 | 0.34 |
| Placebo (n=69) | 3.10±1.365 | – |
The intervention groups were asked how much they observed the perceived effects of the received intervention on a scale from 0 (no effect) to 10 (extremely strong effect). The respective numbers (n) within each group are given and the standard deviations are calculated.
