In scientific writing it is common to use parentheses to refer to the details of statistical analyses at the end of a sentence. However, it is also common to refer to figures or tables this way. Often I find that the same sentence requires both a reference to statistical details and a figure (example below). Should I use adjacent parenthetical references or separate the statistical information from the figure reference with a semicolon?
