Figure 2. Variation in Use of Active Surveillance (AS) Among Men With Low-risk Prostate Cancer.
The circles represent the percentage of patients with low-risk disease managed with AS by each practitioner within each practice with at least 50 low-risk cases managed. Distributions for each level individually (practice and practitioner) are additionally illustrated with hashmarks along the axes. Circle size is proportional to the volume of low-risk prostate cancers managed. The solid and dashed lines indicate the mean and 2 × SDs.
