Dear Louise,
apart from reminding one of the already mentioned Stata routine (please,
type - help metan -) as far as costs are concerned, I would strongly
recommend you to take a look at Glick HA, Doshi JA, Sonnad SS, Polsky D.
Economic Evaluation in Clinical Trials. Oxford: Oxford University Press,
2007: 207-228.
Another thought about a quick (and probably too much) dirty way for dealing
with your issue might be to weight your data for the number of patients
enrolled in each trials.
Sorry I cannot be more helpful.
I do hope that Someone else on the list will chime in with a smarter
insight.
Kind Regards,
Carlo

Oggetto: Re: st: R: Pooled effects for continuous data
Dear Carlo,
Thanks for the information. It is very helpful to know that Stata can be
used for meta-analysis. However, after reading through all the
functions, I still couldn't find anything to caculate the pooled effect
for 'medians and IQR' and the pooled effects for 'different in cost and
its 95% CI'.
For example for hospital length of stay(unit in days):
Study 1 median: 45 IQR: 36, 50
Study 2 median: 32 IQR: 28, 40
Study 3 median: 17 IQR: 12. 22
Study 4 median: 28 IQR: 23, 38
Is there anyway to caculate an effect estimate and a 95% CI of the above
4 studies?
