highly significantp = 0.003
Correlation analysis showed a highly significant relationship (p = 0.003, Pearson r = 0.78) between tumor volume and SFRP2-targeted video signal when omitting the aforementioned “outlier.” Even when this data point was included in the correlation analysis, there was a significant relationship between tumor volume and SFRP2- targeted video signal (p = 0.048, Pearson r = 0.56) as illustrated by the best-fit line in Fig. 5 .
