Please share this question with expert in statistics if you don't know answere.

I am stuck here, as i am working on therapy and trying to evalute the changes in biomarker levels. So I have selected 5 patients and analysed their biomarker levels prior therapy and then after first therapy and followed by 2nd therapy. So as i apply anova results show significant difference in their mean values but due larger difference in their standard deviations i am getting non significant results

like in this table below.

Sample Size Mean Standard Deviation SE of Mean

vb bio 5 314.24 223.53627 99.96846

cb1 bio 5 329.7 215.54712 96.3956

CB II 5 371.6 280.77869 125.56805

So I want to know from all those good statsticians who are well aware about the clinical trial studies.

Please suggest

Am i performing statistics correctly?

Should not i worry about non significant results?

What are the statistical tests I should use?

How will I represent my data for publication purposes?

Please be eloberative in answers?
