I'm unsure about commas and "of which."
Is the sentence below correct, or should I omit the comma before "of
which"? Is the comma necessary? I'm copyediting and can only alter the
text for correct punctuation/grammar.
"This number was reduced to 33, of which only 16 reported an empirical
research study using focus groups."

The comma is both correct and necessary in that particular sentence.
