Abstract
Statistical methods are available for performing a meta-analysis when the response variable of interest is the same in each study. Problems arise when studies exploring a common therapeutic question use different patient response types. This article presents statistical methods for combining studies which involve different classifications of response into ordered categories. The assumptions required for the stratified proportional odds model, on which the analysis is based, are discussed. The approach is illustrated using results from a series of studies investigating the prevention of gastrointestinal damage induced by non-steroidal anti-inflammatory drugs.

This paper examines eight published reviews each reporting results from several related trials in order to evaluate the efficacy of a certain treatment for a specified medical condition and suggests a simple noniterative procedure for characterizing the distribution of treatment effects in a series of studies.

The aim has been not only to review the 65-odd randomized beta blocker trials but also to demonstrate that when many randomized trials have all applied one general approach to treatment, it is often not appropriate to base inference on individual trial results.
Statistics in MedicineA general parametric approach to the meta‐analysis of randomized clinical trials
763 Citations1991Anne Whitehead, John Whitehead
A general parametric approach is presented, which utilizes efficient score statistics and Fisher's information, and relates this to different methods suggested by previous authors.

An alternative display is suggested which represents intervals as points on a bivariate graph, and which has advantages when the data are estimates of odds ratios from studies with a binary response.

598 Citations1988D.Y. Graham, NaurangM Agrawal +1 more
Results provide the first clear indication that NSAID-induced ulcers are preventable, and Mild to moderate, self-limiting diarrhoea was the most frequently reported adverse effect attributed to misoprostol.

Nonsteroidal anti-inflammatory drugs thus appear both to exacerbate an underlying peptic diathesis and to cause de novo ulcers.
Statistics in MedicineBias in the one‐step method for pooling study results
166 Citations1990Sander Greenland, Alberto Salván
The one-step (Peto) method for obtaining pooled effect estimates can yield extremely biased results when applied to unbalanced data, so use of ordinary Mantel-Haenszel, weighted least squares, or maximum likelihood estimates whenever the total number of events is adequate for such methods.

137 Citations1988Frank L. Lanza, Richard L. Aspinall +4 more
It is concluded that misoprostol is highly effective and significantly better than cimetidine in protecting the gastric mucosa from tolmetin-induced injury; however, both agents were highly protective in the duodenum.
GastroenterologyPrevention of Gastroduodenal Injury Induced by Chromic Nonsteroidal Antiinflammatory Drug Therapy
102 Citations1989David Y. Graham
Recent studies have suggested that in those starting NSAID therapy, prophylactic cotreatment with H2-receptor antagonists or sucralfate has minimal or no effect on preventing the development of NSAID-induced gastric ulcers, although duodenal ulcers may be reduced.

102 Citations1986Frank L. Lanza
In conclusion, misoprostol is effective in preventing gastric and duodenal mucosal injury induced by tolmetin and, perhaps, by other nonsteroidal antiinflammatory drugs as well.

It is found that misoprostol protects the gastric and duodenal mucosae against ulceration seen with the administration of both aspirin and the nonsteroidal antiinflammatory drug tolmetin and its cytoprotective properties with those of sucralfate are compared for the first time.

It is concluded that misoprostol can protect the normal gastroduodenum from acute ulceration and reduce the chance of erosion after 1 wk of aspirin ingestion.
