School adjustment changes three gender-adjusted age slope estimates by less than 0.005 ms/year in 122 CNP controls.

In 122 controls from the Consortium for Neuropsychiatric Phenomics (CNP), adding completed years of school to gender-adjusted age models changed the stop-signal reaction time (SSRT) age slopes by 0.004480682, 0.000358537, and -0.003151979 ms/year under three delay rules. The paired 95% participant-bootstrap intervals were [-0.113653125, 0.191574138], [-0.144458995, 0.149830997], and [-0.151922002, 0.142650039]; all included zero and allowed changes larger than the point estimates. These results apply to the specified models and selected adult sample. They do not show equal slopes, no education effect, or a causal effect. The work used 32 STOP trials per participant, lacked measured sound onset, and used completed school years as one education measure. Other education properties, recruitment, task strategy, and unmeasured factors may affect the association. The analysis found no numerical check failures, but its checks were performed by the same investigator and do not establish all stop-process assumptions.
