Mean EBV load in RA patients treated with Tocilizumab.

<p>Epstein Barr virus copy number per 500ng PBMC DNA was assayed in 35 patients under tocilizumab. For every patient, EBV load, median and standard deviation are given every 6 months from the start till 36 months. Four patients accepted to be followed for one more year.</p

EBV load evolution under tocilizumab treatment.

<p>Each black circle indicates EBV load in one patient. Red dots indicate mean EBV load. Mean EBV load evolution is drawn as a blue line +/- 1 standard deviation (dark grey surface) indicating the LOESS (LOcally wEighted Scatter-plot Smoother) regression.</p

Mean EBV load in RA patients treated with Abatacept.

<p>Epstein Barr virus copy number per 500ng PBMC DNA was assayed in 55 patients under abatacept. For all patients, EBV load, median and standard deviation are given every 6 months from the beginning till 36 months. Four patients accepted to be followed for one more year.</p

EBV load evolution under abatacept treatment.

<p>Each black circle represents a patient’s EBV load. Red dots indicate mean EBV load every 6 months. Mean EBV load evolution is drawn as a blue line +/- 1 standard deviation (dark grey surface) displaying the LOESS (LOcally wEighted Scatter-plot Smoother) regression.</p
