The outcome of PTSD was dichotomised into respondents exhibiting or not exhibiting signs of PTSD (cut off ≥ 2.0), and the outcome of depression dichotomised into respondents exhibiting not exhibiting signs of depression (cut off ≥ 1.75), based upon the cut off levels given in the instrument guidelines [ 26].
Based upon the cut off levels given in the instrument guidelines, the outcome of PTSD was dichotomised into respondents exhibiting or not exhibiting signs of PTSD (cut off ≥2.0), and the outcome of depression dichotomised into respondents exhibiting not exhibiting signs of depression (cut off ≥1.75) [ 18].
In the re-estimated model based upon the same principle the cut-off value for Altman, Ohlson and Zmijewski model is taken 0, 0.4 and 0.5 respectively.
These values indicate the high quality of the data, and based upon the PPV calculations, the cut-off for calling a promoter "CREB-bound" in subsequent analyses was chosen to be the Top 5% of the list, corresponding to 1,383 promoters.
The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), were also calculated based upon optimal cut-off scores.
This test was carried out on putative carbapenemase-producing K. pneumoniae isolates based upon their screening cut-off values for meropenem, according to the recommended methods for detection of carbapenemases in Enterobacteriaceae [ 5- 7, 10].
Selection was based upon cut-off scores on a language development test and a nonverbal IQ test, and same-sex pairs were matched within classrooms.
The number of peak groups selected for inclusion can be data independent (i.e., user selected) or data dependent (i.e., based upon a heuristic cut-off).
BMI categories were calculated based upon international standard cut-offs of <18.5 for underweight, <25 for average, <30 for overweight, and ≥30 for obesity [ 16].
We will also calculate the time engaged in light, lifestyle, moderate, and moderate and vigorous intensity physical activity based upon a standardized cut-off of 100-759, 760-1,951, 1,952-5,724, and at least 1,952 counts per minute, respectively.
The relationship between vitamin D level and eGFR was further explored with the study population being divided into quartiles based upon the 25(OH D and population cut-off levels (Table 2).
