Trends in 24-h urinary sodium excretion in the United States, 1957–2003: a systematic review
Open accessAbstract
Background Few studies have examined temporal trends in sodium intake in the US population. Collections of 24-h urine sodium excretions are reliable markers for dietary sodium intake.Objective We examined temporal trends in 24-h urine sodium excretions to estimate temporal trends in sodium intake in the US population.Design We performed a systematic search of English-language articles in MEDLINE for studies that reported collections of 24-h urine sodium excretions in the United States. We estimated mean urine sodium excretions over time for all studies and demographic subgroups.Results We analyzed 38 studies, which dated from 1957 to 2003, and estimated a mean (± SE) 24-h urine sodium excretion per person of 3526 ± 75 mg Na. In a multivariate random-effects model with study year, sex, age, and race, the study year was not associated with any significant change in sodium excretions (coefficient = 154 mg Na · 24 h⁻¹ · 10 y⁻¹; 95% CI: -140, 448 mg Na · 24 h⁻¹ · 10 y⁻¹). In subgroup analyses, there was no significant temporal trend seen in male, female, black, or white study participants.Conclusion Sodium intake in the US adult population appears to be well above current guidelines and does not appear to have decreased with time.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
Few people voluntarily consume a diet as low as 500 mg sodium per day.
“it is rare for anyone to voluntarily follow a diet that low in sodium,19”
From Reducing Dietary Sodium to 1000 mg per Day Reduces Neurovascular Transduction Without Stimulating Sympathetic Outflow (2019) · cites this paper as [19]
The Discussion (page not specified) reports mean 24-hour sodium excretion of about 3,526 mg, well above the 500 mg/day level in the claim. That supports the point that typical intake is much higher, but the paper does not establish how rarely individuals voluntarily follow a 500 mg/day diet. (LLM, conf=0.78)

“Urinary Na and urinary K were converted to mg/day (23 mgNa = 1 mmol Na or 1 mEq Na; 39 mgK = 1 mmol K or 1 mEq K) [44].”
MethodReference intervals for 24 laboratory parameters determined in 24-hour urine collections
Curcio, R., Stettler, H., Suter, P. M., Barman‐Aksözen, J., Saleh, L., Spanaus, K. S., Bochud, M., Minder, E. I., & von Eckardstein, A. (2015) · Clinical Chemistry and Laboratory Medicine (CCLM) · doi:10.1515/cclm-2014-1041 · Cited by 17 · see citing works
“Therefore, the higher median (135 mmol/24 h) and upper reference level probably reflect the higher than recommended salt intake [28] in the Swiss population, which however is in agreement with many other studies [29, 30].”

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.
