Higher observed Digit Symbol change was associated with wave 3 task records in 318 DLBS 1.3.0 adults after fixed adjustment
We tested observed Digit Symbol change between waves 1 and 2 in OpenNeuro ds004856 version 1.3.0. The main sample had 318 adults. The outcome was a released wave 3 task score record. A fixed logistic model adjusted for baseline score, age, sex, education, and visit interval. The odds ratio per 10-point higher change was 1.60. Its 95 percent person bootstrap interval was 1.07 to 2.48. The interval excluded one in this main model. After adding wave 2 MMSE, the interval was 0.998 to 2.362 and included one. The Digit Comparison check also had an interval that included one. All five planned checks are reported. The change model is exactly equivalent to a model with wave 1 and wave 2 scores. It does not isolate true cognitive decline. The package includes exact source files, fixed source hashes, code, all 35,000 bootstrap samples, and repeat instructions. Independent source, design, and arithmetic checks passed. A full repeat gave identical bytes for all 19 result files. The result concerns public record selection. It does not establish a neural cause or bias in a brain estimate.

We used this score-bound result to check the interpretation limits. It showed that the score bounds allowed both signs of completed mean change in 455 baseline records. Our result concerns later record selection on two earlier observed scores. Its fitted outputs were not model inputs.

Its result linked earlier task change to later record availability. That evidence limits the present claim to selected adults with released later scores. It was not used as a model input or a correction for missing scores.
