FMV method: FMV is a complementary method used to assess the degree of endothelial dysfunction in patients with risk factors and their repercussions at the level of the endothelium.
Volume-weighted averages of FMV and non-FMV spots produced model fits that were similar to that obtained with the arithmetic mean (data not shown).
Because some children lacked three FMV or non-FMV samples from different days, we only assessed the sensitivity and specificity of three spot samples in the "any spot sample" group.
For models examining a single unadjusted spot sample (FMV or non-FMV) and its respective 24-hr sample, the predictive power of the model, defined by the coefficient of determination (R), was highest for FMVs [ R for total DAP metabolites (nmol/L) = 0.54 for FMVs vs. 0.39 for non-FMV spots].
The best-fitting models were obtained when the arithmetic mean of an FMV and a non-FMV sample was used to predict the 24-hr values (Table 2).
We report findings separately for FMV samples only, for non-FMV samples only, and for all spot samples.
This analysis included all possible unique pairings of each child's spot samples, and was conducted separately for pairs of FMV spots only, pairs of non-FMV spots only, and for all pairs of spots regardless of FMV status.
Creatinine concentration varied more within children than between children for both FMV (ICC = 0.37) and non-FMV (ICC = 0.22) spot samples.
The primary aim of our study was to show that facemask ventilation (FMV) after NMB was not inferior to FMV prior to NMB with respect to exhaled gas volumes before and after their administration.
The creatinine concentration of spot samples ranged from 9.4 to 213.2 mg/dL (mean, 86.6 mg/dL) for FMV samples and from 4.5 to 158.7 mg/dL (mean, 68.6 mg/dL) for non-FMV samples.
Central tendency measures (e.g., means, medians) for unadjusted concentration values were similar for FMV spot samples and 24-hr samples, which were generally higher than levels in non-FMV spot samples.
