Multifactor Analysis of Asparaginase Response

Check if the same lab product or an alternative is used in the 5 most similar protocols
All statistical analysis was performed with R statistical software (version 2.13.2), Stata 16, and GraphPad Prism 8.4.3 (GraphPad Software, California, USA). Statistical analysis was performed with a two-tailed Student’s t-test between two groups and a one-way analysis of variance (ANOVA) for multiple groups, followed by Tukey’s post hoc test. The univariable analyses were conducted using simple linear regression to assess the association between rectal temperature AUC with anti-ASNase antibodies, basophil activation markers, and ASNase-specific recognition of leukocytes/basophils. Statistically significant factors from the univariable model were included in the multivariable linear regression model. Data are presented as mean ± standard deviation. A P value of less than 0.05 was considered significant and denoted as *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001. Data are shown in mean ± SD.

Statistical analyses were performed in STATA 16 and GraphPad Prism (GraphPad Software Inc., San Diego, CA). P values of less than 0.05 were considered statistically significant. Unpaired t tests and Mann–Whitney U tests were performed, as appropriate.

Exploratory Descriptive Data Analysis

The continuous data were described with the mean and standard deviation (SD) or the median and quartiles (IQR), depending on the distribution and categorical data with the counts and percentage. Given the exploratory nature of the study, no p-values are reported.
GraphPad Prism version 8.2.1 (GraphPad Software, San Diego, CA, USA) and Stata 16 (Colleg Station, TX, USA) were used the computations.

CD68 Density and Air Pollution

Check if the same lab product or an alternative is used in the 5 most similar protocols
We assessed the relationship of CD68 score with the daily average AQI, PM2.5, and wildfire specific PM2.5 via linear regression. Analyses were performed in Stata 16.1 and GraphPad Prism software (version 9.5.0). Two-tailed unpaired Welch’s t-test was performed to compare mean CD68 density against healthy controls among first trimester, second trimester, and term samples.

Survival Analysis of Clinical Outcomes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analyses were performed using GraphPad Prism v9.0 (GraphPad Software Inc., La Jolla, California, USA) and Stata 16.1. Univariate analyses of baseline demographics, clinical, and pathological variables were performed using Pearson's χ2 test and the Mann–Whitney U test. Kaplan–Meier curves were used for survival analysis (OS and PFS) and when required, landmark analysis was performed to reduce immortality bias. Comparisons between groups were analyzed using the log‐rank (Mantel‐Cox) test and univariate Cox proportional hazards regression models. A p value of < 0.05 was considered statically significant.

Comparative Analysis of SIN Biomarkers

Check if the same lab product or an alternative is used in the 5 most similar protocols
The mean ± SD (standard deviation) was used to describe normally distributed data. The differences between the two groups were analyzed using t-tests or rank-sum tests. Paired t-tests were used to compare the results on the first and third days of the MWM. With regard to the RNA-seq results, |log2(fold change)| > 0.2 and adjusted P < 0.05 were set to achieve more DEGs [30 (link)], which have a potential association with SIN. The fold change of each gene was calculated by comparing the standardized read counts of one group to another group (fold change = standardized read counts of one group/standardized read counts of another group). A P < 0.05 was considered a significant difference. All data analyses and statistics were performed with Stata 16.0 (Stata Corporation, USA), and statistical charts were produced by GraphPad Prism 8.0 (GraphPad Software Inc., USA) and Stata 16.0.

Comparative Health Outcomes Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Baseline characteristics were summarized using medians and ranges or means and standard deviations (SD) for continuous variables and frequencies and percentages for categorical variables. Comparisons for variables were performed using Student’s t-test or Mann-Whitney U (for two group comparisons) and the one-way analysis of variance or Kruskall-Wallis (for more than two group comparisons) for continuous numerical data. Categorical data were compared using either χ2tests or Fisher’s exact tests as appropriate. Health state index scores generally range from <0 (where 0 is the value of a health state equivalent to dead; negative values representing values as worse than dead) to 1 (the value of full health) were calculated from individual health profiles using crosswalk value sets for Zimbabwe [16 ]. Statistical analyses were performed using STATA 16.0 and GraphPad Prism 8.0. A p < 0.05 was considered to indicate statistical significance.

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.
