Sigmastat for windows

Results are expressed as means ± SE of at least three independent experiments. Significant differences between groups were determined by one‐way ANOVA and the Student t‐test. All statistical analyses were carried out using the statistical package SigmaStat for Windows (Version 2.03, SPSS, Chicago, IL).

All values are given as mean ± SEM, with the number of samples in parentheses. Statistical comparisons were made using Student’s t test or, and when appropriate, analysis of variance and the Holm–Sidak method for multiple comparisons (p < 0.05 was considered significant) using log values for the qPCR and Western blot data. Calculations and curve fitting were performed using SigmaPlot and SigmaStat for Windows (SPSS Science, Chicago, IL).

All data were analyzed using Sigma Stat for windows (Version 3.0, SPSS Inc., Chicago, IL, USA). The data are expressed as the mean ± SEM. For comparisons among the groups, one-way analysis of variance (ANOVA) and Newman-Keuls multiple comparison tests were performed with P < 0.05 as an indication of statistical significance.

All values are presented as mean ± SEM. Unless otherwise stated, the n values refer to the number of animals. Statistical comparisons were made using Student's t‐test or, when appropriate, analysis of variance (ANOVA) with post hoc testing for multiple comparisons using the Holm‐Sidak method or repeated measured for dependent variables. Calculations and curve fitting were performed using SigmaPlot and SigmaStat for Windows (SPSS Science, Chicago, IL).

Spinal Core software (Mor and Lev-Tov, 2007 (link)) was used to characterize/quantify the LPG output of the spinal cord induced by signal transmission from the brainstem via descending pathways and determine the correlations between the left phrenic and left peripheral muscle nerve discharges and between the left and right muscle nerve discharges during episodes of phrenic nerve discharge. Recorded data were high-pass filtered at 10–20 Hz, rectified, and compressed to a sample rate of 20 Hz. The time series data of left and right tibial nerve discharge and left phrenic and left tibial nerve discharge were used to compute the time domain between the lags from −1 to 1 s and from −2.5 to 2.5 s, respectively, and develop the correlation curves.
Statistical values are expressed as the mean (SE). Differences between means were analyzed using either a statistical software package (Sigma Stat for Windows; SPSS, Chicago, IL, USA) or excel and assessed by either one factor repeated measures ANOVA with a Scheffe post-hoc or the paired t-test. A P < 0.05 was considered to indicate statistical significance.

Due to the nonnormal distribution of the data, nonparametric tests were performed. Data were analyzed by Kruskal-Wallis analysis of variance and Dunn's multiple comparison test. All data are expressed as mean and SEM. Differences were considered significant at P < 0.05. A specific software package (SigmaStat for Windows version 3.00 SPSS Inc., San Jose, CA, USA) was used.

All of the data are expressed as means ± SDs. We analyzed our data with the nonparametric Mann-Whitney U test. The significance level was set at 0.05. A commercial software package (SigmaStat for Windows; SPSS Science, Chicago, IL) was used for the data analysis.
