title: Plotting results of several Bland-Altman analysis
body: <p>I compared several diagnostic methods to a gold standard using Bland-Altman plots. Now I would graphically represent the difference in agreement between each method and the gold standard in one single plot. I'm trying to plot means, confidence intervals and variance derived from the various Bland-Altman plots as horizontal boxplots, but I don't know I to do that.
  I have a dataframe like this:</p>
  
  <pre><code>Method    LCL    mean    UCL    var
  A         -5     4       15     27
  B         -9     2       13     33
  C         -8     4       16     36
  </code></pre>
  
  <p>Thank you very much for your help!</p>
  
  <p>Corrado</p>
