Home blood-pressure self-monitoring and self-titration,
does it really help with Reduced office systolic blood pressure in high-risk hypertension?
research showsThe grade is C. TASMIN-SR excluded three erroneous registrations, leaving 552 participants, and analyzed complete 12-month data from 450. Systolic pressure was 128.2 versus 137.8 mm Hg, adjusted difference -9.2 mm Hg (95% CI -12.7 to -5.7). This exceeded the prespecified 5-mm Hg detectable difference, but blood pressure is a surrogate and 18.5% lacked complete 12-month data, giving C with 54 points.

Useful facts when choosing a product
- The intervention combined home monitoring with prespecified medication self-titration.
- Usual care allowed clinicians to adjust treatment when needed.
- Disclosed equipment support for other research was not shown to be trial-product supply in TASMIN-SR.
What the research actually shows
Fifty-nine UK primary-care practices enrolled 555 people; three erroneous registrations were removed immediately, leaving 552. Treatment was unmasked, but the primary outcome was office pressure measured with an automated device. Only 450 had complete 12-month data, so missingness above 15% is one design limitation. No early stopping was reported. Funding came from NIHR Programme Grants for Applied Research, the NIHR National School of Primary Care Research, and an NIHR career development fellowship. Author disclosures included research equipment received from Omron, Lloyds Healthcare, Microlife, and BP TRU, but the article did not establish that those items were supplied for use in TASMIN-SR, so they were not counted as trial-material support.
Why this is classified as C (54)
The pressure difference exceeded the prespecified detectable difference and public funding was confirmed, but a surrogate endpoint, one trial, and 18.5% missing complete data give C with 54 points.
Counterpoint. Self-titration should be interpreted only with training, safety rules, and a clinician-approved medication plan.
Rejudgment record. Cross-check applied — Cross-checked the main article and protocol for the 552-person analysis set, 450 complete cases, multiple imputation, 5-mm Hg design assumption, NIHR funding, and author disclosures
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced systolic blood pressure at 12 months | C | The adjusted difference was -9.2 mm Hg. |
| Reduced cardiovascular events | ? | The trial was not designed to test reduction in clinical events. |
