Alcohol {ssifs}

Stochastic Search Inconsistency Factor Selection of brief alcohol interventions.

Description

Stochastic Search Inconsistency Factor Selection for the evaluation of the consistency assumption for the network meta-analysis model.

These data are used as an example in Seitidis et al. (2021).

Format

A data frame with the following columns:

studyid	study id
treat1	treatment 1
treat2	treatment 2
m1	mean value of brief alcohol intervention in arm 1
m2	mean value of brief alcohol intervention in arm 2
n1	number of individuals in arm 1
n2	number of individuals in arm 2
sd1	standard deviation of brief alcohol intervention in arm 1
sd2	standard deviation of brief alcohol intervention in arm 2
TE	standardized mean difference of treat1 versus treat2
seTE	standard error of standardized mean difference
