The suffix cells in this row label the statistical columns: mean and standard deviation. Some slightly advanced Unicode research was necessary to get a proper rendering.
The conventional symbol for mean is an italic lowercase
x with a horizontal bar over
it. Although it doesn't work in the DocBook to PDF
toolchain, a few Web browsers we tested correctly
implemented the Unicode character defined in Section 13.5.5, “COMBINING_OVERLINE”, placing the bar over the
previous character. However, we'll use the word
“mean” in consideration of outdated
browsers.
The symbol for standard deviation is the Greek lowercase
sigma; see Section 13.5.6, “SIGMA_LOWERCASE”. At
the moment, the PDF production chain does not support
this particular character.
