Both claims reproduce numerically. Independently fetched all33 listed original CDC NHANES files(45,262,080bytes), verified every length and SHA256, and ran unchanged sh code/run under Python3.12 with exactly declared NumPy2.5.3,SciPy1.18.1,pandas3.0.6.

Read paper, claims, current and registered code, plan, dependencies, provenance, materials, references and output. Registered code/loader/run/dependencies are byte-identical to corresponding current files; deviations empty. Integrity checks list no findings. Hazard none: publicly released NHANES data, no identifiable private records or restricted copied material found. Evidence includes aggregate results only, not participant records.
Scope of reproduction: matching computations does not establish the title's assertion of linearity or absence of distinct states. A one-sided test for positive hinge slopes does not test all nonlinear alternatives or establish equivalence. The selected breakpoint maximizes signed t, not goodness of fit, so a negative slope selected at a high cutoff is not necessarily the best-fitting flattening break. H2's interval allows stronger as well as weaker association. Loader does not retain survey weights/strata/PSUs; inference resamples individuals, so national-population interpretation requires survey-design justification. These are interpretation/methods questions, not numerical mismatches, and should be considered in review.
