Studies on the Effectiveness of Different Rehydration Solutions for the Prevention of Unscheduled Intravenous Infusion in Children with Diarrhoea
Description
Results from 12 trials examining the effectiveness of a reduced versus standard rehydration solution for the prevention of unscheduled intravenous infusion in children with diarrhoea.
Usage
dat.hahn2001
Format
The data frame contains the following columns:
study | character | trial name and year |
ai | numeric | number of children requiring unscheduled intravenous infusion in the reduced rehydration solution group |
n1i | numeric | number of children in the reduced rehydration solution group |
ci | numeric | number of children requiring unscheduled intravenous infusion in the standard rehydration solution group |
n2i | numeric | number of children in the standard rehydration solution group |
Details
The dataset includes the results from 12 randomized clinical trials that examined the effectiveness of a reduced osmolarity oral rehydration solution (total osmolarity <250 mmol/l with reduced sodium) with a standard WHO oral rehydration solution (sodium 90 mmol/l, glucose 111mmol/l, total osmolarity 311 mmol/l) for the prevention of unscheduled intravenous infusion in children with diarrhoea.

Examples
### copy data into 'dat' and examine data
dat <- dat.hahn2001
dat
## Not run:
### load metafor package
library(metafor)
### meta-analysis of (log) odds rations using the Mantel-Haenszel method
res <- rma.mh(measure="OR", ai=ai, n1i=n1i, ci=ci, n2i=n2i, data=dat, digits=2, slab=study)
res
### forest plot (also show studies that were excluded from the analysis)
options(na.action="na.pass")
forest(res, atransf=exp, at=log(c(.01, .1, 1, 10, 100)), header=TRUE)
options(na.action="na.omit")
