Diabetes Data from Andrews and Herzberg
Description
Data on 145 non-obese patients collected at the Stanford Clinical Reseach Center to investigate "the relationship between chemical subclinical and overt nonketotic diabetes. The three primary variables used in the analysis and presented [here] are glucose intolerance, insulin response to oral glucose, and insulin resistance."
From Andrews and Herzberg (1985) book called "Data". See reference.
Format
A data frame with 145 rows and 6 variables
- RelativeWeight
The relative weight of the patient.
- FastingPlasmaGlucose
The fasting plasma glucose level.
- GlucoseArea
This is a measurement of the glucose intolerance as measured by the area under the straightline connecting glucose levels determined from blood samples drawn during a three hour glucose tolerance test following an oral administration of a glucose load.
- InsulinArea
This is a measurement of the insulin response to oral glucose as measured by the area under the straightline connecting insulin levels, again determined from blood samples drawn during a three hour glucose tolerance test following an oral administration of a glucose load.
- SSPG
The steady state plasma glucose (SSPG) determined after chemical suppression of endogenous insulin secretion. This is a measure of insulin resistance.
- ClinClass
Clinical classification of each patient, by the contemporary (1979) medical criteria, into one of three groups: "Overt" diabetic, "Chemical" diabetic, or "Normal".
The row order of the values match the "Patient Number" given in the source table.
Details
This is a dataset from the "Data" book by Andrews and Herzberg (1985) Chapter 36, pp. 215-220 Table 36.1
A more complete description can be found there. An extract from the source follows.
The purpose of the data was to investigate
"the relationship between chemical subclinical and overt nonketotic diabetes in 145 non-obese adult subjects. The three primary variables used in the analysis and presented [here] are glucose intolerance, insulin response to oral glucose, and insulin resistance. The first two [of these] variables are the areas under the straightline connecting glucose and insulin levels, respectively, determined from blood samples drawn during a three hour glucose tolerance test following an oral administration of a glucose load. [These are variables GlucoseArea and InsulinArea, respectively.] Insulin resistance is measured by the steady state plasma glucose (SSPG) determined afterchemical suppression of endogenous insulin secretion. In addition, the relative weight and fasting plasma glucose were measured for each individual at the Stanford Clinical Reseach Center and are included [here]"
Each row of diabetes is a patient, and the row number is the "Patient Number" from Andrews and Herzberg.
