Abstract

BACKGROUND: A diminished number of nephrons has been proposed as one of the factors contributing to the development of primary hypertension. METHODS: To test this hypothesis, we used a three-dimensional stereologic method to compare the number and volume of glomeruli in 10 middle-aged white patients (age range, 35 to 59 years) with a history of primary hypertension or left ventricular hypertrophy (or both) and renal arteriolar lesions with the number and volume in 10 normotensive subjects matched for sex, age, height, and weight. All 20 subjects had died in accidents. RESULTS: Patients with hypertension had significantly fewer glomeruli per kidney than matched normotensive controls (median, 702,379 vs. 1,429,200). Patients with hypertension also had a significantly greater glomerular volume than did the controls (median, 6.50x10(-3) mm3 vs. 2.79x10(-3) mm3; P<0.001) but very few obsolescent glomeruli. CONCLUSIONS: The data support the hypothesis that the number of nephrons is reduced in white patients with primary hypertension.

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.
