Meta-analysis of rare events requires special considerations regarding which statistical method to use. This is because standard meta-analytical models are not well suited for the task, especially when some of the identified studies have reported zero events in one or more treatment groups.

Meta-analysis has been widely used to synthesize information from related studies to achieve reliable findings. However, in studies of rare events, the event counts are often low or even zero, and so standard meta-analysis methods such as fixed-effect models with continuity correction may cause substantial bias in estimation.

because they are time-to-event markers. Once the author of a meta-analysis has assembled a large number of studies, it is important to select the right ones. Which studies are included or excluded.

A recent meta-analysis concluded that the addition of bevacizumab to cancer therapy increased the risk of gastrointestinal (GI) perforation and vascular events (arterial and venous) when all tumours were studied together, but results were heterogeneous when data were studied by tumour type [12, 13].

Conceptually, a meta-analysis uses a statistical approach to combine the results from multiple studies in an effort to increase power (over individual studies), improve estimates of the size of the effect and/or to resolve uncertainty when reports disagree. A meta-analysis is a statistical overview of the results from one or more systematic.

In the context of rare events data, such as observing few, zero, or zero total (i.e., zero events in both arms) outcomes in binomial trials or 2 × 2 tables, most existing meta-analysis methods rely on the large-sample approximations which may yield invalid inference.

16.9.3 Studies with no events. The standard practice in meta-analysis of odds ratios and risk ratios is to exclude studies from the meta-analysis where there are no events in both arms.
