Effect formula

Effect definition

Unit of reference value

m

Unscaled (e.g. occupancy, %)

%

m - mbl

Change from baseline (raw)

Same unit as endpoint

m - mctrl

Change from control (raw)

Same unit as endpoint

100*((m -mbl) / mbl)

Change from baseline (%)

%

100*((m - mctrl) / (mctrl)

Change from control (%)

%

100*(Nsbj,grp/Ngrp – Nsbj,ctrl /Nctrl)

Diff in % Event (percentage points)

% (percentage points)

  1. M; mean response of endpoint at the corresponding exposure level.
  2. mbl; mean response of endpoint at the baseline.
  3. mctrl; mean response of endpoint at the corresponding exposure level in the control group.
  4. Ngrp; total number of subjects in the group.
  5. Nsbj,grp; number of subjects that experienced the event in the group.
  6. Nctrl; number of subjects in the control group.
  7. Nsbj,ctrl; number of subjects that experienced the event in the control group.
