For the BSI, ROC cut-off scores approximated cut-off scores with optimal sensitivity, as reported by De Beurs and Zitman (2006).
As reported previously, the continuous variable miR-200a was analysed as dichotomous variable according to approximate cut off point (Atzpodien et al, 2003).
On this basis, we eliminated from consideration a variety of taxa, using an approximate cut-off of raccoon (Procyon lotor) size, including ungulates, Manidae, Felidae, and others.
However, pay scales often overlap between longer-serving general doctors and more junior specialists and an approximate cut-off was used in some cases.
However, several studies have recommended 10 as an approximate cut-off representing a small change, 20 for a moderate change and 30 for a large change on scales of the SF-36 [ 28, 29].
In the present study, cognitive level was dichotomized in terms of mental retardation (MR) yes/no, which correspond to the approximate cut-off for IQ greater or less than 70 (Table 1).
Three groupings were defined using the approximate cut-offs for chromosome-wise and genome-wide significance previously calculated by permutation testing for this data (chromosome-wise, 0.05, F = 5; chromosome-wise, 0.01, F = 7; genome-wide, 0.01, F = 10; [ 1- 4]).
Comparisons of the prevalence of MetS and its components by psoriasis status were done in age-stratified analysis (30 44, 45 59 and 60 79 years), according to an approximate cut-off for premenopause in women (< 45 years) and premature cardiovascular disease (< 60 years).
Our results show that at approximate cut-off of 0.5 mmol of UCr/h either 10 or 24 h post-transplant there is a very high positive and negative predictive value for early allograft function (89% positive and 91% negative predictive value 10 h post-transplant, see Table 3).
The TDC-criterion of successful/unsuccessful treatment approximated the cut-off separating two patient subgroups in a bimodal post-treatment distribution of TDC-values.
Pretreated standard grade, regenerated cellulose dialysis membrane with an approximate molecular weight cut off (MWCO) of 3.5 kDa was obtained from Spectrum Laboratories.
