Table 1 The \(2\times 2\) table for the event reporting counts of drug j and AE i
| Â | Drug j | No Drug j | Total |
|---|---|---|---|
AE i | \(n_{ij}\) | \(n_{i\cdot }-n_{ij}\) | \(n_{i\cdot }\) |
No AE i | \(n_{\cdot j}-n_{ij}\) | \(n_{\cdot \cdot }-n_{i\cdot }-n_{\cdot j}+n_{ij}\) | \(n_{\cdot \cdot }-n_{i\cdot }\) |
Total | \(n_{\cdot j}\) | \(n_{\cdot \cdot }-n_{\cdot j}\) | \(n_{..}\) |
