“Segmentation is driven by machine learning algorithms.”
source quote (p.9)
“The TRAQinform IQ software operates in a secure cloud environment.”
Validation studies (2)
Standalone
n=31 patients
endpoints: The limits of repeatability endpoint estimated the interval within which 95% of repeated measurements are expected to lie when clinically relevant change is lacking.
Reader study (MRMC)
n=103 patients
endpoints: distinguish each of 103 patients as positive versus negative for progression based on presentation of the locally generated radiology report without and then with adjunctive presentation of the TRAQinform Report.; quantify positive percent agreement (PPA, representing patients classified as positive by both the panel and an oncologist), negative percent agreement (NPA; representing patients classified as negative by both the panel and an oncologist), and the 95% confidence interval (95%CI) for overall percent agreement (OPA; prevalence-biased PPA and NPA aggregation).
Reported performance (3 observations)

“PPA was 14/18=78%”
source quote (p.12)
“NPA was 5/14=36%.”
