## Figure 8.
Funnel plot of contrast-induced nephropathy (with estimated unpublished studies). Trials are depicted by circles with the random-effects log odds ratio shown along
the horizontal axis and precision in estimating this effect (reciprocal standard error)
along the vertical axis. The Trim and Fill method was used to calculate the true center
of the funnel (indicated by the vertical line) after filling in estimates of unpublished
studies (depicted with black dots). The empty diamond indicates the original confidence
intervals of the log odds ratio; the black diamond indicates the corresponding values
when the additional imputed studies are also considered.
