Table 3 Observed and imputed HbA1c and FBG across 1–3-month, 4–6-month, and 8–12-month follow-up periods after transplant for heart transplantation patients who did not have pre-transplant DM.
Variable | Observed data | Imputed/perfect collection | ||||
---|---|---|---|---|---|---|
n | Missing values | Mean* | n | Missing values | Mean* | |
1–3 month HbA1c | 19 | 82 | 6.6/49 | 101 | 0 | 6.1/43 |
4–6 month HbA1c | 28 | 73 | 6.7/50 | 101 | 0 | 5.8/40 |
8–12 month HbA1c | 43 | 58 | 5.6/38 | 101 | 0 | 5.6/38 |
1–3 month FBG | 99 | 2 | 125/6.9 | 101 | 0 | 125/6.9 |
4–6 month FBG | 98 | 3 | 107/5.9 | 101 | 0 | 107/5.9 |
8–12 month FBG | 99 | 2 | 105/5.8 | 101 | 0 | 105/5.8 |
* Displayed as (%/mmol per mol) for HbA1c and (mg per dl/mmol per l) for FBG. 95% confidence intervals not displayed, but were the same between observed and imputed variables |
