Table 2. Grit and Measures of Glycemic and Cholesterol Control.
| Outcomea | Mean (SD) | Patients, No. | Change in Outcome Associated With a 1-SD Increase in the Short Grit Scale Score (95% CI) | |
|---|---|---|---|---|
| Univariate | After Multivariate Adjustmentb | |||
| Triglycerides, mg/dL | 174.9 (132.8) | 425 | −17.8 (−30.5 to −5.1) | −18.5 (−32.2 to −4.8) |
| Cholesterol, mg/dL | 175.0 (47.8) | 425 | −6.3 (−10.9 to −1.7) | −5.2 (−10.0 to −0.4) |
| Glycated hemoglobin, % | 8.17 (1.99) | 425 | −0.17 (−0.36 to 0.02) | −0.07 (−0.26 to 0.13) |
| Glucose, mg/dL | 145.1 (60.1) | 433 | −5.1 (−10.8 to 0.7) | −6.3 (−12.3 to −0.2) |
SI conversion factors: To convert triclycerides to millimoles per liter, multiply by 0.0113; cholesterol to millimoles per liter, multiply by 0.0259; glycated hemoglobin to proportion of total hemoglobin, multiply by 0.01; and glucose to millimoles per liter, multiply by 0.0555.

Estimates were computed with separate regressions. Sample sizes range between 392 and 422 patients.

Covariates included an indicator variable for sex, cubic polynomials for years of schooling and number of years with diabetes, and categorical variables for several measures of socioeconomic status determined by hospital social workers according to household income, dwelling characteristics, and occupation of the primary income earner.
