The phrase "and differences were analysed" is correct and usable in written English.
It can be used in contexts where you are discussing the examination or evaluation of differences in data, results, or observations.
Example: "The study focused on various factors affecting the outcome, and differences were analysed to determine their significance."
Alternatives: "and differences were examined" or "and differences were assessed".
Survival curves were constructed according to the Kaplan Mayer method and differences were analysed with the log-rank test.
Frequencies, means and standard deviations were calculated and differences were analysed using an unpaired t-test for normally distributed variables.
Survival curves were calculated by the Kaplan Meier method and differences were analysed by the log-rank test.
The Kaplan Meier method (Kaplan and Meier, 1958) was used to evaluate survival, and differences were analysed by the Log-rank test (Peto et al, 1977).
Probabilities of progression-free and overall survival were estimated using the Kaplan Meier method and differences were analysed using the log-rank test.
Continuous data were presented as the median (interquartile), differences were analysed by Mann-Whitney test, categorical data were expressed in percentages (n/N) and differences were analysed by χ test or Fischer's exact test.
Moreover, we found distinct differences in the phenolic compound composition of T- and S-oaks, and these differences were analysed in more detail, as described above.
The median was calculated for both primary tumours and metastases/recurrent tumours and statistical differences were analysed using the Fisher's Exact test.
In this study, a field test was designed and performed by adopting a particular PP array to collect sounding data under different 'infinite' electrode distances, and the differences were analysed in the apparent resistivity curves calculated with different geometric coefficients.
The median was calculated for both primary tumours and lymph node micrometastases and statistical differences were analysed using the Fisher's Exact test.
Data are means ± SD (n ≥ 7) and statistical differences were analysed with the one-way ANOVA test followed by Dunnett's post hoc test as compared with 0.5 h uptake time (c) or with non-blocked 1 h uptake time (d); *p < 0.05, **p < 0.01, #p < 0.001.
