(a) Box plot presenting the interrater variability of the 4 radiologists’ from the experimentally preset gold standard as a function of size and number of simulated microcalcifications scattered on the 48 films. Statistical outliers are labeled with an asterisk () or a dot (). Criterion: “Number" of detectable microcalcifications as a function of the experimentally preset size of silica beads.
