Survival Analysis of Anterior ETT Restorations

Check if the same lab product or an alternative is used in the 5 most similar protocols
The data were statistically analyzed using SPSS v.22 for Mac (SPSS Inc., Chicago, IL, USA) and STATA v.17 for Mac (Stata Corp., College Station, TX, USA) with a significance level of p-value <0.05. Descriptive statistics were used to describe the data distribution. Fisher's exact test was used to compare the data distribution between the resin composite and crown groups. The survival rate against fracture of the anterior ETT with resin composite and crown restorations were compared using Kaplan-Meier survival analysis and the Tarone-Ware test.
When analysing the possible prognostic factors, the hazard ratios were non-proportional. Hence, a multivariable, non-proportional hazard model was used in a full model and a predictive model to explain and predict any prognostic factors with a p-value of <0.05 in the Tarone-Ware test.
For the subgroup analysis in the resin composite group and the crown group, the Kaplan-Meier survival analysis and the Tarone-Ware test were used to analyze the survival rates and possible prognostic factors.

Statistical analysis was carried out with SPSS v.22 for Mac (SPSS, United States). Data were presented as mean ± SD. Groups were compared with variance tests (comparisons between untreated and treated mice). Differences were considered statistically significant with a P-value < 0.05.

Survival Analysis of Breast Cancer Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Kaplan–Meier survival analyses were undertaken using SPSS v.22 for Mac (IBM Corp., Armonk, New York, NY, USA). IHC scores were coded as low (≤the median value) or high (>the median value). Mice with MDA-MB-468 tumors below the ethical endpoint of 1,000 mm3 at day 82 after cell implantation were regarded as survivors. For HCC1806 tumors, all mice had reached the ethical endpoint before 12 weeks (i.e., there were no survivors). Linear and non-linear (exponential) correlations between IHC scores were fitted using Deltagraph v.7 (Red Rock Software, Salt Lake City, UT, USA) with P values calculated by SPSS.

Combination Drug Synergy Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
CompuSyn v1.0 software (ComboSyn Inc., Paramus, NJ, USA) was used to calculate the Chou-Talalay Combination Index (CI), where CI < 1indicates synergism and CI > 1 indicates antagonism [25 (link)]. All other statistical analyses were performed using SPSS v.22 for Mac (IBM Corp, Armonk, NY, USA). Effects of drug treatment on tumor IHC staining scores were calculated using 1-factor ANOVA followed by Tukey’s post hoc test. Pearson’s correlations among IHC staining scores are reported with two-tailed P values.

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.
