How do I use regression to obtain a confidence interval for a log odds using meta-analysis?

This [attachment:james.pdf paper] proposes using a weighted linear regression to produce confidence intervals for a pooled estimate of log odds from various studies. The regression uses the log odds from each study as the outcome, the inverse of the sample size of each study as the only predictor and weights each study using the inverse of the variance of the log odds (denoted by 'WLS weight' in the SPSS linear regression procedure). The variance of each log odds is found by simply summing the inverses of each of the four cells in the table of frequencies which are used to compute the odds ratio for a particular study (see an example [:FAQ/oddsr:here.])
