Sarah's initial information was from a website that offered cupping as a service. Because of this, the credibility of the source would be considered low $($low$/$high$).$

The website did offer a graph from a scientific study. However, no source was offered. Because of this, the credibility of the source would be considered low $($low$/$high$).$

The graph compares the quality of life for individuals that have received cupping and for those that have not received cupping.

The average scores for cupping are higher $($lower$/$higher$)$ than for no cupping.

The error bars overlap between the group that received cupping and the group that received no cupping.

This means that the results are not $($are$/$are not$)$ significant, so based on these data, there is no $($is$/$is no$)$ significant difference in the quality of life with the addition of therapeutic cupping.
