Network meta-analysis comparing the effects after Laparoscopic Heller myotomy.

Description

Network meta-analysis dataset comparing the effects after Laparoscopic Heller myotomy.

Format

A data frame in contrast format with the following columns:

logOR	log odds ratio
selogOR	standard error of log odds ratio
id	study ID
t1	first treatment
t2	second treatment

Details

The dataset compares the effects after Laparoscopic Heller myotomy. The outcome is the number of individuals with successful rates at 12 months. These data are in contrast format with effect size odds ratio (OR) and its standard error. Arm-level data can be found in Schoenberg et al. (2013).
