Values of the LF differences between baseline and last 30 minutes of hemodialysis.

<p>Values of the LF differences between baseline and last 30 minutes of hemodialysis in the three groups by excluding diabetes (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120167#pone.0120167.t003" target="_blank">Table 3</a>). The circles represent the singular patients. The errorbar represents the median and the 25^th and 75^th percentile (patients are grouped by the tertiles of FO_pre/ECW% values). Note the increase in LF in the first tertile. The outliers are inserted in the picture at a different scale in order to focus the attention to the errorbars.</p
