All three diagnosis contrast intervals for GO time change contain ±0.020 source units in 124 ds000030 participants.

In 124 participants from OpenNeuro ds000030 version 1.0.0, we compared diagnosis differences in correct GO response-time change between the first and second halves of a stop-signal task run. We selected common event schedules before outcome exclusions, used 13 of 39 schedules, and fit paired ordinary least squares models with schedule, diagnosis, age, and source gender terms. All three Bonferroni 95% confidence intervals for patient-minus-control change contained both ±0.020 source units; the individual 95% intervals did too. On the assumed seconds scale, these bounds are ±20 ms. The precision condition was therefore not met, and the intervals do not show equality or a diagnosis cause. The analyzed common sample included 46 control, 25 ADHD, 25 bipolar, and 28 schizophrenia participants. Results use correct GO responses only, and response-time units are assumed because the source field has no explicit unit declaration. This is one run per participant, not a repeat-session reliability study; the selected sample was not checked for similarity to a clinical population. The source reports no further common-sample exclusion for age or source gender and retains sensitivity results, schedule-removal ranges, checks, and limitations in the full text and supporting files.
