mean => Arithmetic mean
standar dev. => Sample standard deviation
ci. max 90%, ci.min => confidence interval at confidence level 90% => it means that mean value of the distribution lies with 90% propability in interval ci_min-ci_max
geom. mean => Geometric mean
median => Second quartile = cuts data set in half = 50th percentile
first quartile => cuts off lowest 25% of data = 25th percentile
third quartile => cuts off highest 25% of data, or lowest 75% = 75th percentile
minimum => Lowest value of data set
maximum => Hightest value of data set
baseline set1 difference => Difference of medians of both sets in percennt. Arithmetic means are used in detail mode instead.
ttest p-value => Student's t-test p-value = probability the both data sets are equal
ttest equality => If p-value is higher than 0.1, data sets are considered being equal with 90% probability. Otherwise the data sets are considered being different.
Linear regression of all results regression line is in y = ax form, b coeficient is zero.
