Table 2.

Calcium score versus pretest risk.

Calcium score	No = low pretest risk	N = medium pretest risk	N = high pretest risk
Zero calcium score, male	18	20	21
Zero calcium score, female	114	52	29
Calcium score 1–400, male	11	24	76
Calcium score 1–400, female	15	15	17
Calcium score >400, male	1	2	30
Calcium score >400, female	3	5	9

This table shows the numbers of patients with a particular calcium score range and their pretest risk, which is classified as low, medium, or high. The majority of patients with a zero calcium score have a low pretest risk, but significant numbers of patients have a zero calcium score with a high pretest risk.
