Abstract

We studied systolic and diastolic function of the left and right ventricles in obese male subjects. Obese subjects had increased left ventricular mass and normal left ventricular systolic and diastolic function. They also had impaired right ventricular relaxation and right ventricular filling.

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

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Many published studies have concluded that obesity is independently associated with LV hypertrophy.

    “Many published studies have concluded that obesity is independently associated with LV hypertrophy (22, 28, 63, 72, 116, 235, 242, 266, 279, 284, 377).”

    From Cardiac remodeling in obesity (2008) · cites this paper as [266]

  • Available published data do not consistently support the hypothesis that RV enlargement results from obstructive sleep apnea and chronic pulmonary hypertension.

    “Although it seems likely that RV enlargement could result from obstructive sleep apnea and chronic pulmonary hypertension (see below), the available published data surprisingly do not consistently support this hypothesis (266, 378).”

    From Cardiac remodeling in obesity (2008) · cites this paper as [266]

  • Some studies have found reduced early diastolic (E-wave) velocities while others have found them unchanged in obese subjects.

    “Some studies have found reduced early diastolic (E-wave) velocities (155) while others have found them to be unchanged (242, 266, 274, 279, 314).”

    From Cardiac remodeling in obesity (2008) · cites this paper as [266]

  • Findings on LV ejection fraction in obese subjects are variable, with studies reporting depressed, normal, or supernormal EF.

    “Various authors have reported depressed LV ejection fraction (EF) (15, 68, 100), normal EF (22, 111, 116, 191, 242, 266, 279, 377), and supernormal EF (28, 155, 274, 375) in obese subjects.”

    From Cardiac remodeling in obesity (2008) · cites this paper as [266]

  • One of these studies did find altered RV diastolic filling characteristics.

    “However, one of these did find altered RV diastolic filling characteristics (266).”

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.
