Comparison with new findings based on Read coded Health Check attendance
| Outcome | DIDM estimator (95% CI) | |
|---|---|---|
| Main findings in paper | New findings* | |
| QRISK2 (10-yr CVD risk) | −0.21 (−0.24 to −0.19) | −0.10 (−0.13 to −0.07) |
| Systolic blood pressure (mm Hg) | −2.51 (−2.77 to −2.25) | −1.40 (− 1.72 to −1.07) |
| Diastolic blood pressure (mm Hg) | −1.46 (−1.62 to −1.29) | −0.90 (− 1.09 to −0.70) |
| Body mass index (kg/m2) | −0.27 (−0.34 to −0.20) | −0.19 (−0.26 to −0.13) |
| Total cholesterol (mmol/L) | −0.15 (−0.18 to −0.13) | −0.09 (−0.11 to −0.06) |
| Smoking prevalence (%) | −0.11 (−0.35 to 0.13) | −0.14 (−0.45 to 0.17) |
| Statin prescribing (%) | 3.83 (3.52 to 4.14) | 2.56 (2.19 to 2.93) |
| Antihypertensive prescribing (%) | 1.37 (1.08 to 1.66) | 0.37 (−0.002 to 0.74) |
Note: CI = confidence interval, DIDM = difference-in-differences matching.
