Figure 1. Box plot and scatter plot of circRNA signal value variation in OA and NOA samples. (A). The distribution of circRNAs for the nine samples. (OA: obstructive azoospermia; NOA: non-obstructive azoospermia). (B). Scatter plot showed variations in circRNA expression between OA and NOA samples. CircRNAs located above the top green line and below the bottom green line were more than 1.5-fold between OA and NOA samples.
