The mean SSRT difference between schizophrenia and control groups changes by 18.91 ms between two delay fields in 166 selected CNP sessions.
In 166 selected CNP sessions (44 schizophrenia and 122 control), the mean SSRT difference changed by 18.91 ms between StopSignalDelay and LadderTime (pointwise participant-bootstrap 95% interval 3.34 to 35.48 ms). This is unadjusted arithmetic under two unvalidated delay conventions, calculated with a fixed integration estimator. The primary eligibility screen retained 241 sessions across four diagnostic groups. Results depend on sample selection; all sessions had 32 STOP trials, below a 2019 consensus rule of thumb of at least 50 in favorable conditions. The event fields do not establish actual tone timing. The intervals do not account for trial-level error, timing error, or population selection, and the group estimates do not establish biological causes.
