^*Model 1: Naïve model (only community use in the model); Model 2: adjusted by sqrt(#of calls); Model 3: adjusted by sqrt(# of FAQs read); Model 4: adjusted by both sqrt(# of calls) and sqrt(# of FAQs read).

^**ORs are calculated as 1st group/2nd group, where pairs are expressed as "1st group vs. 2nd group".
