| Variable | 3–4 Stents (n = 1578) | Control (n = 707,396) | P Value | 3–4 Stents vs Control, Adjusted β (95% CI) | P Value |
| LOS, d | 4.41 ± 4.80 | 3.63 ± 4.30 | <0.001 | 0.09 (−0.12 ≤ β ≤ 0.29) | 0.404 |
| Total reimbursement | $24,482.56 ± $16,592.60 | $21,534.89 ± $15,880.22 | <0.001 | $449.88 (−301.56 ≤ β ≤ 1201.32) | 0.241 |
| Total hospital cost | $93,435.13 ± $79,140.99 | $87,427.30 ± $77,287.80 | 0.003 | $18.82 (−3629.25 ≤ β ≤ 3666.89) | 0.992 |
