Schlichtkrull and his co-worker (1965) introduced the M-value for the evaluation of bloodsugar control in diabetic patients treated with insulin. Their table of MBSBS was made for theblood sugar value determined by the method of Hagedorn and Jensen and this table is not used for the true blood sugar value.
In this report, a new table of MBSBS is proposed so that it can be applied for the value obtained by the true blood sugar method such as glucose-oxidase method. The table was calculated by the following formula.
MBS/BS=10×logBS/1003
Namely, the new table was made on the premise that the ideal blood sugar is 100 mg/dl. The tables were also made if the ideal blood sugar was 90 or 110 mg/dl i. e., the denominator was 90 or 110. The comparison of these MBSBS tables revealed that the M-value becomes greater if the denominator becomes smaller. Hence, the M-value would be different if the table of Schlichtkrull et al. or the new table is used. To compare this difference, the M-value was calculated in the two ways, 1) by the new table (M1), 2) by the table of Schlichtkrull et al., but the value was read at the 20 mg/dl-high corresponding value (M2). These two procedure were applied for 287 diurnal blood sugar curves of 44 diabetic inpatients, in which the blood sugar estimation was made at 7 a.m., 9 a.m., 11 a.m., 2 p.m., 4: 30 p.m., 7 p.m. and 10 p.m. The result showed that M1-value was always greater than M2-value and the following relationship was obtained by the regression analysis.
Y (M1) =1.36X (M2)-0.64
Schlichtkrull et al. defined the criteria of the blood sugar control as good in the group having the M-value≤18, fair with 19-31, and poor with≥32. These values must be changed as good with≤24, fair with 25-42, and poor with≥43, when the new table is used.
