  1. (a): The data obtained at the first electrophysiological examination are shown: 1st column: patient number, 2nd column FP DFSO with number of days from sepsis onset until FP was first examined; 3rd column: 1st minimal CMAP amplitude at the indicated nerves before serial stimulation; 4th column: maximal CMAP amplitudes upon serial stimulation at the indicated nerves; 5th column: duration of maximal CMAPs at the indicated nerves; 6th column: distal motor latencies obtained with maximal CMAPs - peroneal and tibial nerves; 7th column: Nerve conduction velocities obtained with maximal CMAPs at the indicated nerves
  2. (b): All data are from the last follow-up examination: 1st column: patient number; 2nd column: days after the 1st electrophysiological examination; 3rd column: minimal CMAP amplitude at the indicated nerves before serial stimulation; 4th column: maximal CMAP amplitudes upon serial stimulation at the indicated nerves; 5th column: duration of maximal CMAPs at the indicated nerves; 6th column: distal motor latencies obtained with maximal CMAPs – peroneal and tibial nerves; 7th column: clinical outcome; 8th column spontaneous activity obtained with needle EMG
  3. Fibs fibrillation potentials, * here only 3 serial stimuli could be applied, FP-DML distal motor latency as measured with facilitated max CMAPs, FP-max CMAP maximal CMAP amplitude reached during FP, FP-NCV nerve conduction was calculated from distal and proximal facilitated maximal CMAPs in the indicated nerves, n.d. not done, Per peroneal nerve values (listed below the tibial nerve values); needle EMG, PSW positive sharp waves, SpA spontaneous activity, Tib tibial nerve values listed (above peroneal values), Uln ulnar nerve; Outcome at day indicated: +; ++; +++ mildly-moderately-markedly improved muscle weakness. Patients 1 and 2 deceased. For normal values see Additional file 3
