The background cut off standard was set to be 20 fold of the input signals [ 18].
Two commonly used cut-off standards for low QOL have been proposed, namely, "70% of the maximum score" and "one SD below the mean" [ 19, 20].
Based on BMI and WC cut-offs standards associated with the Chinese population, the prevalence of overweight, obesity and abdominal obesity was 27.8%, 5.7% and 38.8%, respectively, in rural Hanzhong, Shaanxi province.
We calculated standard deviations for parallel samples, set cut-off standard to one, and quantified gene expression based on normalization with the control and self-normalization in parallel samples.
For each specimen relative light unit/cutoff values were calculated as the ratio of the specimen luminescence relative to the luminescence of the 1.0 pg/ml HPV-16 cut-off standard and reflect a semi-quantitative value of the cumulative viral burden from one or more of the examined genotypes.
*97 hours was used as cut off point as standard infusion time was 96±± 1 hr.
Nutritional status was established based on World Health Organization recommendations (WHO), International Obesity Task Force (IOTF), Center for Diseases Control (USA-CDC) cut off values and local standards, respective.
RNA-seq detected a greater total number of DE genes than the microarray (1,037 versus 374, respectively, using the standard cut off criteria).
A full CART algorithm adds nodes until they are homogenous or contains few observations (≥5 is the standard cut off in S-Plus).
To assess reliability, internal consistency was evaluated by calculating the Cronbach's α statistic using the standard cut off point of 0.7 [ 17].
