	S1	S2	S3
R1
Sensitivity	82.8% (716/865) [80.1%, 85.2%]	88.9% (769/865) [86.6%, 90.9%]	88.7% (767/865) [86.3%, 90.7%]
FPS	0.16 (31/198) [0.11, 0.22]	0.21 (42/198) [0.16, 0.28]	0.22 (43/198) [0.16, 0.28]
R2
Sensitivity	83.9% (726/865) [81.3%, 86.3%]	88.7% (767/865) [86.3%, 90.7%]	88.8% (768/865) [86.5%, 90.8%]
FPS	0.19 (38/198) [0.14, 0.26]	0.13 (26/198) [0.089, 0.19]	0.091 (18/198) [0.056, 0.14]

DL, deep learning; FPS, false-positive per scan.

The data in parentheses represent the detected fractures over the total number of fractures or false-positive over total scans for the sensitivity and FPS, respectively.

The data in brackets represent the 95% confidence intervals.

S1, S2, and S3 represent the reading session without DL, DL as a concurrent reader, and DL as a second reader, respectively.

R1 and R2 indicate reader 1 and reader 2, respectively.
