Table 2:

Number of Stones Visually Detected and Characterized According to Confidence of Detection by Using 1-mm Images

Note.—Data are numbers; data in parentheses are percentage and data in brackets are 95% confidence intervals pertaining to the percentages. One-millimeter images were used for all conditions. The odds of detecting a definitely present stone with photon-counting detector low-energy threshold are 1.29 times that when using energy-integrating detector mixed kilovolt images. EID = energy-integrating detector, PCD = photon-counting detector, T_L = low-energy threshold.

*Data in parentheses are 95% confidence interval.
