A positive reaction was indicated when the signal:cut-off (S CO) exceeded 1.5.
This cut-off value exceeds the physiologic increased procalcitonin median value of 2,38 ng/mL, observed in uninfected infants in the second day of life (data unpublished).
For double FIT sampling, we considered the FIT positive when the cut-off level exceeded 50 ng/ml in at least one out of two samples.
For the analysis of the ELISA data, the titer of the sera was defined as the last serial dilution with an OD405 value exceeding the Cut Off 0.275, corresponding to the mean + 1.5 SD of the background values of positive sera at serum dilutions of 1 50.

A similarity search with known proteins identified 39,200 different genes to be expressed during limb regeneration with a cut-off E-value exceeding 10-5.
Individuals with excessive head motion were excluded from analysis (cut-off criteria: deviations exceeding 3 mm; sudden jumps greater than 2 mm).
When the cut-off of SUV exceeded 1.8, specificity and PPV of F-FDG PET/CT were almost 100%, but sensitivity notably decreased to 36% or lower.
As for the other markers, we found that, at baseline, 2/75 patients exceeded the OC cut-off, while 8/75 (10.6%) exceeded the CTx cut-off.
