Logistic regression analyses (final column) indicated that a difference of 1 standard deviation in levels of weight, height, and BMI approximately doubled the odds (range, 2.0 to 2.6) that a girl would experience menarche before age 12 y.
A one standard deviation change in levels of complement substrate (factor B), regulator (factor D), and activation products (Ba and C3d) was associated with an approximately 5-fold increase in AMD risk (Fig. 3).
These reductions of standard deviations mean reduction of unevenness in levels of understanding of the session contents and in levels of difficulties of following class among participants.
The greatest deviations in the level of measured plasma ultrafiltrate acids from that observed in the control group were seen in the patients within the lactic acidosis and 'unexplained acidosis' groups.
However, we found no significant difference in plasma ACT and SLPI levels between subjects with deficiency of AAT and subjects with wild type AAT (age and gender matched controls) N-number of subjects SD, standard deviation We found no significant difference in plasma levels of SLPI and ACT between deficiency and normal AAT subjects in the absence of COPD (Table 2A).
Based on means, standard deviations, and levels of physical activity achieved in previous trials, we calculated we needed a sample size of 880 to detect a minimum difference between the groups of 7% change in the proportion of women reaching the target level of 150 minutes of at least moderate intensity physical activity each week, allowing for a 10% attrition rate (α=0.05, 80% power).
Disagreements between ionospheric models and observed TEC are found during post-sunset and post-midnight periods, with TEC deviation in the level of 11 14 TECU can be anticipated at 95% probability.
A deviation in the level of agreement, "strongly agree" or "agree," between rounds was evident in most statements, and was not dependent on changes to statement phrasing (Table 7).
1) We calculated the t-score for each gene by comparing its expression levels in the two sample groups, t = μ 1 - μ 2 δ 1 2 / n 1 + δ 2 2 / n 2, where μ1, μ2 are means and δ1, δ2 are standard deviations of expression levels of the gene in case and control samples.
DS was defined as (1) DS = M x − M y S x + S y, where M x and S x represent mean and standard deviation of expression levels of genes in a pathway x and M y and S y in a pathway y.
