Spss 19.0 statistical software package

At 7, 14 21 days after HTL-WW treatment (DAT), three plants per treatments have been sampled for shoot biomass determination. At the same time points, SPAD index was measured with a MINOLTA chlorophyll meter (SPAD 502-Plus). The flower biomass was measured at the end of the experiment (after 21 days).
Data were analysed by test-t for pairwise comparison of means (at P < 0.05) using SPSS 19.0 statistical software package (SPSS Inc., Cary, NC, United States).

Each investigator coded most of the answers for computer analysis using standard rules. SPSS 19.0 statistical software package (SPSS Inc., Chicago, IL, USA) was used for analysis. Separate analyses were performed for UC cases and their matched controls and for CD cases and their matched controls. Descriptive variables are presented as medians (interquartile range, IQR), and categorical variables are presented as frequencies with percentages. Each environmental factor was first tested by univariate analysis with odds ratios (OR) and 95% confidence intervals (95% CI). In multivariate analysis, based on conditional logistic regression, variables with a p-value < 0.05 in the univariate analyses were proposed for entry into the model. Rates of ‘unsure’ responses were compared between cases and controls to assess for differential reporting. A p-value of < 0.05 was considered significant.

All of the parameters described above were measured 90 days after the plants were subjected to soil Cd treatments. SPSS 19.0 statistical software package (SPSS, Chicago, IL, United States) were used in the study to perform the statistical analyses. For each treatment, the mean values with standard deviation (±SD) are shown in the figures and tables. The parameters were analyzed by one-way analysis of variance (ANOVA, p < 0.05), followed by Duncan’s multiple range tests. The graphs were created using Origin 9.0 software (Origin Lab, United States).

All statistical analyses were performed using the SPSS 19.0 statistical software package (SPSS Inc., IL, United States). The differences in PTPRO expression immunoreactivity score were compared by the Mann-Whitney U test. The statistical significance of differences was evaluated with a t-test, and means, standard error, and 95% confidence intervals were calculated using GraphPad Prism 5 (GraphPad Software Inc., San Diego, CA). Correlations between PTPRO expression and clinicopathological factors were investigated using the χ² test. The correlation coefficient between variables was performed using Spearman’s rank test. Survival curves were generated using the Kaplan-Meier estimates, and the statistical significance of differences between curves was evaluated by the log-rank test. Furthermore, hazard ratios (HR) and 95% confidence intervals (CI), which were computed from univariate and multivariable Cox proportional hazards regression models (approximate proportionality was verified by visual examination of the Kaplan–Meier estimates), were used to assess associations between relapse-free survival and clinicopathological characteristics. A p-value of less than 0.05 was considered to be significant, and all tests were 2-sided.
