Description Usage Format References

A dataset consisting of 14 empirical studies used for a meta-analysis in Anderson et al. (2016). The outcome of interest was risk of hospital admission of patients with coronary heart disease within follow up duration. Compared was exercise-based cardiac rehabilitation (treatment) with usual care (control).

A data frame with 14 rows and 15 variables:

- study_name
short name of each study

- year
publication year of each study

- ai
number of patients in the treatment group with an event (hospital admission) for each study.

- bi
number of patients in the treatment group with no event for each study.

- ci
number of patients in the control group with an event (hospital admission) for each study.

- di
number of patients in the control group with no event for each study.

- n1i
number of patients in the treatment group for each study, (ai + bi).

- n2i
number of patients in the control group for each study, (ci + di).

- rr
relative risk of an event for treatment vs. control, (ai/n1i)/(ci/n2i).

- or
odds ratio of an event for treatment vs. control, (ai*di)/(bi*ci).

- logrr
natural logarithm of the relative risk (

`rr`

) for meta-analysis.- logrr_se
standard error of the natural logarithm of the relative risk for meta-analysis, sqrt(1/ai + 1/ci - 1/(ai + bi) - 1/(ci + di)).

- logor
natural logarithm of the odds ratio (

`or`

) for meta-analysis.- logor_se
standard error of the natural logarithm of the odds ratio for meta-analysis, sqrt(1/ai + 1/bi +1/ci + 1/di).

- followup
dichotomous moderator: follow up duration.
