Similarly, higher treatment response rates in CIDP-DM patients were associated only for those fulfilling 2 or more 10% cut off study criteria (67% vs. 35%, p = 0.01), whereas this association was demonstrated in CIDP+DM patients fulfilling 2 or more 30% cut off study criteria (89% vs. 36%, p = 0.01)(Table 2). This evidence concerns the gene PMP22 and diabetes mellitus.
