Correlation between gene clusters and Complete BUSCOs

Hi,

I am a beginner to the concepts of biosynthetic gene clusters (BGCs) and BUSCOs.
I ran antiSMASH and BUSCO analysis for my data.
As a primary results, I tested for correlation between the No. of BGCs and complete BUSCOs.
I observed a negative correlation between the same.

I would like to know whether there is actually any correlation between the both and if yes, how do I test my data accordingly.

It would be great if anyone could help me out with this.

Thank you..
