DRLs are often established at the 75th percentile of dose distributions obtained from standard-sized adult patients (70 ± 15 kg) to ensure benchmark applicability across facilities.
“DRLs are often established at the 75th percentile of dose distributions obtained from standard-sized adult patients (70 ± 15 kg) to ensure benchmark applicability across facilities.65”
From Computed Tomography Diagnostic Reference Levels Worldwide and in Jordan: Implications for Patient Dose Reduction (2026) · cites this paper as [65]
The introductory passage (section headed “M M REHANI, PhD”; page unavailable) says DRLs commonly use the 75th percentile of mean doses from patients near a standard size, typically 70 kg. It does not specify 70 ± 15 kg, and it describes the purpose as detecting high-dose outliers rather than ensuring benchmark applicability across facilities. (LLM, conf=0.88)

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.
