Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Percentage format only
Numbers are presented in percentage format (e.g., 35%, 0.2%) only.
Presentation of drug efficacy and side effect data
Data presented in 1 of 5 numeric formats in each arm: percentage only, fixed frequency only, variable frequency, variable combination and fixed combination format.
Fixed frequency format only
Numbers are presented in fixed frequency format only (5 out of 1000, 0.6 out of 1000). Denominators remains the same for each number.
Presentation of drug efficacy and side effect data
Data presented in 1 of 5 numeric formats in each arm: percentage only, fixed frequency only, variable frequency, variable combination and fixed combination format.
Variable frequency format
Frequency denominators are adjusted to keep the numerator greater than 1, so they may change throughout the survey (e.g., 6 out of 1000, 42 out of 100)
Presentation of drug efficacy and side effect data
Data presented in 1 of 5 numeric formats in each arm: percentage only, fixed frequency only, variable frequency, variable combination and fixed combination format.
Fixed combination format
Numbers are presented with both percentages and frequencies, and frequency denominators remain fixed (e.g., \_ out of 1000).
Presentation of drug efficacy and side effect data
Data presented in 1 of 5 numeric formats in each arm: percentage only, fixed frequency only, variable frequency, variable combination and fixed combination format.
Variable combination format
Numbers are presented with both percentages and frequencies, but frequency denominators may vary (e.g., \_ out of 1000, \_ out of 100).
Presentation of drug efficacy and side effect data
Data presented in 1 of 5 numeric formats in each arm: percentage only, fixed frequency only, variable frequency, variable combination and fixed combination format.
