Results indicate that high percentages of one or more "abnormal" scores were obtained, irrespective of the cut-off criterion.
Thus, the number of tests in a test battery and the cut-off criterion applied affect the number of low scores: that is, as more tests are administered and less stringent [e.g., 25th percentile (z = −0.67)] cut-off scores are applied, then more "abnormal" scores will be obtained by healthy individuals [ 12, 14, 15].
According to the Gaussian distribution, the number of low scores varies as a function of the cut-off score the higher the cut-off score, the more abnormal test scores are required to diagnose cognitive impairment.
Abnormal nerve conduction score was defined as one or more abnormal Z scores in two or more nerves, based on sural nerve amplitude, tibial and peroneal nerve conduction velocity (NCV), tibial amplitude, increased F-wave minimum latency, or absent F-waves.
Compared with the 25OHD sufficient group (25OHD>50 nmol l−1), those who were 25OHD deficient had significantly higher (more abnormal) SRS scores (mid-gestation n=2866, β=0.06, P<0.001; cord blood n=1712, β=0.03, P=0.01).
Furthermore, patients with DD had lower peak heart rate achieved, slower heart rate recovery, more abnormal Duke Treadmill scores, lower overall METs achieved and percentage METs ≥7 as compared with patients with normal baseline diastolic function (table 3).
Abnormal NCS were defined as one or more abnormal Z score in two or more nerves, based on sural nerve amplitude (antidromic stimulation), tibial and peroneal NCV, tibial amplitude, increased F-wave minimum latency (F-min), and absent F-waves (only considered abnormal in tibial nerve).
An impact score of 1 (here also referred to as borderline score) is interpreted as possible but not definite caseness whereas a score of 2 or more (an abnormal score) indicates probable caseness.
Indeed, children without headaches of mothers with frequent headaches were more likely to have abnormal scores of internalizing (42.1 vs. 17.9 %) and total score symptoms (31.6 vs. 14.5 %) (Table 3).
Children with migraine were more likely to present abnormal scores in several of the CBCL scales, relative to children without migraine, and maternal migraine status contributed little to the model.
Comparing to controls, children with migraine of mother without headaches were more likely to have abnormal scores in the following domains of CBCL (relative risk and confidence intervals are displayed on the table only for ease of reading): somatic (20.3 vs. 3.0%%), anxiety-depressive (12.6 vs. 3.4%%), attention (15.9 vs. 6.1%%), internalizing (49.2 vs. 17.9 %) and total score (32.5 vs. 14.5 %).
