Distribution of mMNSI total score and DPNP^a rate by DSPN stage^b.

	Total	No DSPN	Minimal DSPN	Subclinical DSPN	DSPN
Patient no.	145	64	19	18	44
mMNSI, total score
DPNP, (%)	16 (11.0)	5 (7.8)	0 (0.0)	1 (5.6)	10 (22.7)

Abbreviations: mMNSI: modified Michigan Neuropathy Screening Instrument; DSPN: distal symmetrical polyneuropathy; DPNP: diabetic peripheral neuropathic pain; NCS: nerve conduction studies; DN4: Douleur Neuropathique; SD: standard deviations. ^aDPNP indicates patients with . ^bNo DSPN, patients with mMNSI total and NCS severity score 0-1; minimal DSPN, patients with mMNSI total and NCS severity score 0-1; subclinical DSPN, patients with mMNSI total and NCS severity ; DSPN, patients with mMNSI total and NCS severity . Data were compared by DSPN stage against no DSPN, using the two-sample -test for the mMNSI total score and the chi-squared test for the DPNP rate. , , and indicate significant difference as compared with no DSPN.
