The column “Difference ± SEM” contains the difference between the homeopathic preparations and controls, which indicates the effect of homeopathic preparation on the UV-light transmission. The 95% CI does not include the zero value for statistically significant differences. There were significant differences between some of the CuSO4 homeopathic preparations and controls. Thus, the measurements at both locations that were done some days after preparation showed significant differences between homeopathic preparations and controls but not the measurements performed on the first day after preparation. The UV-transmission was also lower for both SiO2 and S, but not significant. The pooled data, once all data, once only the data for CuSO4 and once only for data from Lab 2 exhibit significant differences in transmission between homeopathic preparations and controls. Asterisk signifies a significant Levene's test, which indicates that the variance was significantly different between homeopathic preparation and control. Bold typeface indicates significance P < .05 .
