The highest number of true positive and the lowest false positive results were used to represent cut off values by comparing the points with maximum Youden index (J = max c [Se (c) + Sp (c) – 1]).
(11 where Ωa represents reference frequency, and Ωb represents cut-off frequency.
As many as 92% had MUAMC within the reference range, while 5% had MUAMC between the 5th and 10th percentile, and 3% had values under the 5th percentile, which represents cut-off values for moderate and serious undernutrition, respectively [ 17].
Horizontal blue lines represent cut-off value for standardized residuals and the vertical blue line shows the warning value for leverage values obtained from hat matrix.
Statistical heterogeneity among studies was evaluated using the I 2 statistic, where values of 25%, 500 %and75%5 % represent cut-off points for low, moderate and high degrees of heterogeneity, respectively [ 23].
In his memoires of the Egyptian campaign under Napoleon, he wrote appreciatively about the surgical skills of the ancient Egyptians, and provided the following information from his visit to Thebes: "On the ceilings and walls of these temples are bas-reliefs, representing limbs, cut off with instruments very similar to those used at present in surgery, for amputating.
For a low-pass raised-cosine filter given by H ( k ) = 1 k ≤ ( 1 − β ) k 0 cos 2 Π 4 β k 0 ( k − ( 1 − β ) k 0 ) ( 1 − β ) k 0 < k ≤ ( 1 + β ) k 0 0 otherwise (28). in which k represents frequency bin, k0 represents the cut-off frequency bin of the filter, and β is the roll-off factor (0 ≤ β ≤ 1).
(11 where ωc represents the cut-off frequency and Nf represents the filter order.
The value of 1 represents the cut-off frequency, and 0.5 represents the half of the cut-off frequency, namely, Nyquist frequency.
Although the term 'low' has been used for categorisation of depression it should be noted that this represents the cut-off score of 16, above which individuals are regarded as being at higher risk of clinical depression i.e. 43% of the sample had a score above this cut-off.
The value of PI of 1.3 represents a cut-off point that can be used in clinical practice.
