Research questions, findings and source-linked methodological records across evidence synthesis and secondary analysis.
Source-linked research questions, method choices and bounded findings. These are research-development artifacts, not peer-reviewed publications. The underlying code and documentation are linked for scrutiny.
HINTS 7: adjusted OR 1.83 (95% CI 1.42–2.34; n=5,183). The HINTS 6+7 interaction does not establish a change across cycles (OR 1.20, p=0.330).
Research insight: association within one cycle and difference between cycles are distinct statistical questions.
Device MIMS movement density and reported leisure-time activity represent related yet non-identical constructs (n=4,726).
Method insight: survey weighting, sensitivity to valid-day rules and why neither measure can simply be treated as a gold standard.
A selected 15-study map contrasting phases, active comparators, actual exposure and physical-activity maintenance.
Working insight: added features can be redundant; preserving activity can differ from producing new gains.
The HINTS and NHANES analyses provide code, saved results and validation reports. The 11 October cross-project review was a desk audit, not an independently executed raw-data replication. Two systematic-review projects remain in progress; unverified public identifiers are not asserted.
A jointly maintained SISFIT open-research resource mapping selected adult digital physical-activity interventions across intervention components, phase structure, active comparators, adaptation, engagement/exposure and maintenance.
