Recomputing p-values needs the paper’s full text.

Verification

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • During a time when a population's health status is improving, life expectancy at birth e(0) should increase.

    “Empirical studies20,46 of these life table metrics, as illustrated in Figs. 4 and 5a,b, are consistent with the following expected changes in the life table parameters during a time when a population’s health status is improving.(i)Life expectancy at birth, e(0), should increase.”
  • During a time when a population's health status is improving, life table entropy H* should increase.

    “(ii)Life table entropy, H*, a positive correlate of the mean lifespan under ideal conditions, should increase.”
  • During a time when a population's health status is improving, lifespan inequality Φ* should decrease.

    “(iii)Lifespan inequality, Φ*, should decrease.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
