15 16 The following data were extracted from each study: the first author's last name, publication year, study duration, participant's sex and age, body mass index, sample size, SFA, MUFA, PUFA, linoleic acid, α-linolenic acid, dietary cholesterol content of intervention protocol or dietary protocol, caloric intake, information on supplements, primary outcomes, number of events.
We assessed comparative model fit using the following indices: Sample-Size Adjusted Bayesian Information Criterion (SS-BIC), the Akaike's Information Criterion AICC), and entropy.
Using the ratio between the widths of confidence interval and reference interval as the relative precision index, optimal sample size procedures are presented for precise interval estimation under expected ratio and tolerance probability considerations.
BMI represents body mass index, n sample size, SD standard deviation Table 2 shows the associations of each OA site with the five patterns of dietary exposure.
To detect a small to moderate effect (0.4) of VAS and EQ-5D index, a sample size of 100 is needed [ 48].
However, due to the restraints on resources and time, this research is subject to improvement on index selection, sample size, and methodology; we will increase the sample size reasonably and improve the research methods in the later experiment which could provide a real-time dynamic variation of three-dimensional images for clinical accurate diagnosis.
There were no significant correlations between diversity indices and longitude or between diversity indices and sample size (Additional file 1).
Tucker-Lewis index (TLI): TLI is a non-normed fit index (NNFI) that partly overcomes the disadvantages of NFI and also proposes a fit index independent of sample size (Bentler and Bonett 1980; Bentler 1990).
Only the association with aerobic fitness was statistically significant, but if our participants are representative of jockeys and track-work riders in general, the association with measures of anaerobic fitness would have been statistically significant for peak and mean power per kilogram of body mass and for fatigue index had the sample size been just one or two times greater (data not shown).
Given the significance of the relationships between the independent and dependent variables, the likely explanation for the variation in the fit indices is likely sample size restricting the statistical power related to the fit indices calculations (Hooper et al. 2008).
In humans, high fetuin-A concentrations are associated with insulin sensitivity determined during the euglycemic-hyperinsulinemic clamp or HOMA-IR index in small sample size nondiabetic subjects [12], [13].
