Prognostic Analysis of Survival Outcomes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Clinical and biological features between groups were compared using the Fisher exact test for categorical data and the nonparametric Mann-Whitney U or t tests for continuous variables; continuous variables from related samples were compared using the Wilcoxon test. A p value <0.05 was considered significant. OS was calculated from the date of diagnosis to the date of death or last follow-up. TTT was calculated from the date of diagnosis to the date of first treatment or last follow-up, considering disease-unrelated deaths as competing events. The log-rank test was used to compare Kaplan-Meier curves of OS; the Gray test was used to compare cumulative incidence curves of TTT. Multivariate analyses of prognostic factors were modeled using Cox and Fine-Gray regression models as previously described [34 (link)]. Statistical analyses were carried out using GraphPad Prism version 7.0 for Windows (GraphPad Software, San Diego, CA) and XLSTAT version 2014. 5.03 (AddinsoftTM).

Prognostic Significance of Protein Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
The data presented represent the mean with standard deviation (SD) of at least three independent experiments. The statistical significance was determined by Student’s t-test and by one-way and two-way ANOVA with Bonferroni’s posttest; p < 0.05. Patients were divided in three groups according to high, moderate, or low expression of protein target. The Kaplan–Meier (KM) method was also used for OS and progression-free survival (PFS) analysis. For univariate and multivariate analysis of significance, the log-rank test or Cox analysis was used (Graph Pad and XLSTAT). A value of p < 0.05 was considered as statistically significant. The statistical analysis of IC50 levels was performed using Prism 5.0a (Graph Pad).

Statistical Analysis of Experimental Data

All data are presented as the mean ± standard deviation (SD) of individual experimental groups. Pairs of groups were compared using the Mann–Whitney U test. Differences were considered significant when the P value was as follows: p < 0.05; p < 0.01; p < 0.001. Statistical analyses were carried out using Prism 4.0 from GraphPad and XLSTAT.

Statistical analysis was performed using XLSTAT and Prism 4.0 (GraphPad). Data were analyzed using the Mann-Whitney U test to compare pairs of groups. The results are expressed as the mean ± SD of individual experimental groups. Differences were considered significant when the P-value was < 0.05.

Whitefly Infestation Response in Cassava

Check if the same lab product or an alternative is used in the 5 most similar protocols
Quality and general overview of data was revised using principal component analysis (SIMCA v15, Umetrics). Data matrices were analysed using two strategies: (i) By pair-wise comparisons of genotypes per time-point using multiple t-test comparisons corrected by Holm-Sidak post-hoc test (α = 0.05); (ii) by investigating how each variety responds to the infestation of the whitefly by using analysis of variance (ANOVA) and multiple mean comparison Tukey HSD, Bonferroni or Dunnett post-hoc tests using pre-infestation time-point (T0) as control. Statistical analysis and graphs were performed using the XLSTAT, GraphPad Prism 7 and MetaboAnalyst online platform.
Results were painted over bespoken pathways constructed from KEGG and Manihot esculenta-PlantCyc dedicated databases and literature references.

Statistical Analysis of Biological Experiments

R version 3.2.3, XLSTAT version 1.2 or Prism 6.0 software (GraphPad) were used for statistical analyses. The level of significance was set at p < 0.05. The type of statistical test used is provided in the figure legends. All experiments were performed using independent biological samples with the exception of the ChIP-seq. All experiments were repeated at least three times in an independent manner with the exception of the microarray experiment. PCA analysis was performed on XLSTAT version 1.2, based on a Pearson correlation matrix. First and second component (F1 and F2 axis) were used to generate a correlation circle where the variables (genes) were plotted as vectors according to their correlation with F1 and F2 axis.
The figures were prepared using Adobe Illustrator (Adobe Systems).

All data are expressed as the mean ± standard deviation for each experimental group. Pairs of groups are compared using the Mann–Whitney U test. Data are considered to be statistically significant when the P value is as follows: P < 0.05; P < 0.01; P < 0.001. All statistical analyses are performed using GraphPad Prism 4.0 and XLSTAT.

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.
