µFTIR maps obtained with calcium phosphate apatite features were collected for samples: PiCa, PiCa Mg2, PiCa Mg5, Pi4, Pi4 Mg2, Pi4 Mg5.
<p>The scale bar corresponds to 500 µm while the amplitude is between 0 and 10. Due to extended acquisition times, some maps were divided in 2 areas. The map size is 2000 µm x 4500 µm.</p
Flow chart for sample selection (RRT: Renal replacement therapy).
<p>Relative to the excluded patients, the included patients did not differ significantly in terms of gender and the prevalence of congestive heart failure but were older (+1 year, p<0.001), had a slight lower eGFR at initiation (-0.2ml/min, p = 0.03), were less likely to have diabetes (-2%, p<0.002) and had different patterns of initially treated conditions or primary renal disease (Table A in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0176616#pone.0176616.s001" target="_blank">S1 File</a>).</p
