Meta-analysis data set including 22 randomized, controlled clinical trials on the prevention of respiratory tract infections by selective decontamination of the digestive tract in intensive care unit patients. The patients in the treated group received oral antibiotics, and those in the control groups received no prophylaxis.
A data frame with 22 observations on the following 7 variables:
character string, label of the study
integer, number of patients who became cases of respiratory tract infections among those receiving antibiotics
integer, number of patients receiving antibiotics
integer, number of patients who became cases of respiratory tract infections among those receiving no prophylaxis
integer, number of patients receiving no prophylaxis (control group)
numeric, log odds ratio estimates for the individual trials
numeric, standard error of the log odds ratio estimate for the individual trials
The data set was originally analyzed by the Selective Decontamination of the Digestive Tract Trialists' Collaborative Group (1993) and reanalyzed by Bodnar et al. (2017). Overall, 3836 patients are included in these 22 trials.
The log odds ratio estimates and standard errors were computed using the
escalc function in the
metafor using the option of adding 0.5 to all cells in tables including zeros (argument
as described in Bodnar et al. (2017).
