Vital CEMET statistics based on 1322 multi-element-analysis of 33 metals in spot urine

This Excel file presents critical statistics for the Chelated Metal Expression Test (CEMET), conducted after intravenous provocation with GSH, Na-Ca-EDTA, and DMPS. It serves as a reference for evaluating CEMET results and establishing normal ranges for 33 potentially hazardous metals relevant to environmental medicine.

The dataset includes 1322 urine multi-element analyses (700 females, 622 males) from a representative Central European population, with metals measured via ICP-MS. The analyzed elements are Ag, Al, As, Au, B, Ba, Be, Bi, Cd, Co, Cr, Cs, Cu, Fe, Gd, Hg, Li, Mn, Mo, Ni, Pb, Pd, Pt, Sb, Se, Sn, Sr, Ti, Tl, U, V, Zn, Zr.

The file offers statistical insights for raw metal values (µg/L) and creatinine-corrected values (µg/g CRN) across men, women, and combined data. This includes geometric/arithmetic means (± SD), SEM, minimum/maximum values, percentiles (5th, 25th, 50th, 75th, 95th), detection limits, samples ≥ and < DL.

Imputation techniques (log-normal or weighted exponential) were applied to address values below detection limits. The dataset represents both raw and imputed values. Creatinine levels (0.25 to 3.5 g/L) helped to minimize dilution bias.
