Funnel Plot showing the Peto log odds ratio on the x-axis and the standard error on the y-axis.

<p>There is no obvious asymmetry to suggest missing unpublished trials.</p

Forest plot including only trials with a prespecified protocol for oral volume expansion showing resolution of heterogeneity.

Forest plot of randomized trials meeting inclusion criteria.

<p>Size of data markers indicates the weight of the trial. Trials are ordered by year.</p

Metaregression of the proportion of patients with diabetes in a trial on the X-axis against the log Peto odds ratio on the Y-axis.

<p>This shows that there is a significant trend to greater benefit with oral volume expansion in trials with a higher proportion of diabetic patients.</p

Metaregression of the average total contrast dose administered on the X-axis against the log Peto odds ratio on the Y-axis.

<p>This shows that there is a significant trend towards lower CI-AKI with intravenous expansion compared to oral expansion as the contrast dose increases.</p

Patient and BP devices characteristics separated according to over- or underestimation.

Scatterplots of actual mean systolic and diastolic blood pressures with the two methods.

<p>Lines are drawn, for illustration purposes only, through a threshold of 140 mm Hg (for systolic) and 80 mm Hg (for diastolic).</p
