Tip: We aren't comparing the effect of the treatment (tx) to the effect of placebo. We are *defining* the effect as the *difference* in outcome between those allocated to standard of care (SoC) + tx to those allocated to SoC + placebo, where placebo is used for blinding.

We're not really even doing that. We can't always use a placebo. We're trying to make any differences between the groups attributable only to treatment or chance. We can quantify chance so we can indirectly quantify the treatment effect. And the indirectness is what confuses the hell out of people.
