PRIMARY outcome

Timeframe: 30 minutes each at the Baseline and the Follow-Up visit at Month 18

Inhibitory performance was assessed using the computerized Stroop task at the Baseline and at the Follow-Up assessments. The difference in response time (RT) between the Baseline and the Follow-Up Stages was calculated as the index of the inhibitory performance.

PRIMARY outcome

Timeframe: 30 minutes each at the Baseline and the Follow-Up visit at Month 18

The neuroelectrical activities (P3 component) during the Stroop task were recorded and analyzed using the Neuroscan system. The difference in P3 amplitudes of incongruent trials between the Baseline and the Follow-Up Stages was calculated as the index of the neuroelectrical index.

SECONDARY outcome

Timeframe: 30 minutes each at the Baseline and the Follow-Up visit at Month 18

Participants' aerobic fitness was estimated using the submaximal cycle ergometer test at the baseline and at the follow-up assessments. The difference in maximum oxygen consumption (VO2 max) between the Baseline and the Follow-Up Stages was calculated as the index of aerobic fitness.

OTHER_PRE_SPECIFIED outcome

Timeframe: 30 minutes each at the Baseline and the Follow-Up Stages.

Population: The Tower of London Test, a pre-specified Primary Outcome Measure, was not administered to any participants due to unforeseen constraints in practical resource availability at the study sites (i.e., unavailability of required test materials and time limitations that precluded its inclusion within the study timeline). Consequently, no data was collected for this outcome measure.

Higher order executive performance was assessed using the Tower of London Test at the baseline and at the follow-up assessments. Changes in higher order executive performance from Baseline to the Follow-Up Stages were assessed.
