Inositol 1,4,5-trisphosphate receptor type 1 autoantibodies in paraneoplastic and non-paraneoplastic peripheral neuropathy

Table 3 Electroneuronography findings in patient 3 at 6 months (m6), 9 months (m9) and 32 months (m32) after onset, demonstrating axonal and demyelinating sensorimotor poly(radiculo)neuropathy with, as in patient 1, lost and delayed F waves of the upper and lower extremities
