Evaluating Renal Fibrosis with ARFI Imaging

Check if the same lab product or an alternative is used in the 5 most similar protocols
SPSS version 13.0 statistical software package (SPSS, Chicago, IL, USA) was used for data analysis. The mean SWVs, renal length, parenchymal thickness, and interlobar arterial RI among different groups were analyzed by one-way analysis of variance (ANOVA) and the Student-Newman-Keuls test. Correlations between ARFI and conventional US parameters with variables (glomerular sclerosis, tubulointerstitial damage, vascular sclerosis, histologic scores, serum creatinine, and e-GFR) were analyzed by using Pearson's correlation coefficients.
The diagnostic performance of ARFI imaging and conventional US in identifying renal histological fibrosis was assessed by receiver operating characteristic (ROC) curves. The optimal cut-off values for the prediction of different group with CKD were chosen to maximize the sum of sensitivity and specificity. Sensitivity, specificity, and positive and negative predictive values were calculated after the cut-off values were optimized. P<0.05 was considered statistically significant.
Intraclass correlation coefficients (ICCs) were used to assess the intra- and inter-observer reliability of the SWV measurements. Agreement was indicative of poor (ICC<0.40), fair to good (ICC = 0.40 to 0.75) or excellent (ICC>0.75).

Statistical Analysis of Continuous and Categorical Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analysis was performed using the SPSS version 13.0 statistical software package (SPSS Inc., Chicago, IL, USA). Continuous data were expressed as the mean ± standard deviation (SD) or median (inter-quartile range). Categorical variables were presented as the number and the percentages. Continuous variables were compared with the use of Student's t-test or Mann-Whitney U-test. Categorical variables were compared with Chi-square test or Fisher's exact test. Statistical significance was defined as a value of P < 0.05.

Statistical Analysis of Biomedical Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analyses were performed using the SPSS version 13.0 statistical software package (SPSS, Inc.). Statistical tests for data analysis included log rank test, χ2 test, Spearman-rank correlation test, Student's 2-tailed t-test and one-way ANOVA followed by Newman-Keuls test. Multivariate statistical analysis was performed using a Cox regression model. Data are presented as the mean ± SD. P<0.05 was considered to indicate a statistically significant difference.

Biomarkers for Sepsis Severity Assessment

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analysis was performed using the SPSS version 13.0 statistical software package (SPSS Inc., Chicago Illinois, USA). Continuous data were expressed as the mean ± standard deviation when normally distributed. Non-normally distributed variables were expressed as medians and interquartile ranges. Categorical variables were presented as numbers and percentages. Differences in clinical and laboratory findings were assessed using unpaired t-tests, Mann-Whitney U tests and chi-square tests or exact Fisher’s tests, when appropriate. A correlation analysis between PCT, hs-CRP and SOFA score was performed using a nonparametric Spearman’s test. Receiver operating characteristic (ROC) curves and the areas under each respective curve were calculated. The maximum PCT and CRP concentrations, and the white blood cell (WBC) in the first 12 h were used to calculate the ROC curves. Statistical significance was defined as p<0.05.

Genetic Risk Assessment Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Differences in genotype and allele frequencies between patients and controls were tested using a chi-square (χ 2 ) test or two-tailed Fisher's test when the number of expected cases was small. The differences were considered significant at p < 0.05. Genetic risks were assessed by calculating odds ratios (OR) with 95% confidence intervals (95% CI). Bonferroni corrections were used for multiple comparisons. Statistical analysis was performed using the SPSS version 13.0 statistical software package (SPSS Inc, Chicago, IL, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
