Final answer:
The percentage of patients with mets at the time of diagnosis can be determined using the provided information about the percentage of the population diagnosed within specific ranges.
Step-by-step explanation:
The question is asking for the percentage of patients who have metastasis (mets) at the time of diagnosis. Metastasis refers to the spread of cancer from its original site to other parts of the body. To determine the percentage, you can use the information given about the percentage of the population diagnosed within specific ranges. Each range represents a percentage. For example, if 38.45-47.45% of the population is diagnosed, it means that 38.45% to 47.45% of patients have mets at the time of diagnosis.
