1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundFewer than 40% of persons with hypertension in the United States have adequate blood pressure (BP) control.

objectiveTo compare 2 self-management interventions for improving BP control among hypertensive patients.

designA 2 x 2 randomized trial, stratified by enrollment site and patient health literacy status, with 2-year follow-up. (ClinicalTrials.gov registration number: NCT00123058).

setting2 university-affiliated primary care clinics. PATIENTS: 636 hypertensive patients.

interventionA centralized, blinded, and stratified randomization algorithm was used to randomly assign eligible patients to receive usual care, a behavioral intervention (bimonthly tailored, nurse-administered telephone intervention targeting hypertension-related behaviors), home BP monitoring 3 times weekly, or the behavioral intervention plus home BP monitoring. MEASUREMENTS: The primary outcome was BP control at 6-month intervals over 24 months.

results475 patients (75%) completed the 24-month BP follow-up. At 24 months, improvements in the proportion of patients with BP control relative to the usual care group were 4.3% (95% CI, -4.5% to 12.9%) in the behavioral intervention group, 7.6% (CI, -1.9% to 17.0%) in the home BP monitoring group, and 11.0% (CI, 1.9%, 19.8%) in the combined intervention group. Relative to usual care, the 24-month difference in systolic BP was 0.6 mm Hg (CI, -2.2 to 3.4 mm Hg) for the behavioral intervention group, -0.6 mm Hg (CI, -3.6 to 2.3 mm Hg) for the BP monitoring group, and -3.9 mm Hg (CI, -6.9 to -0.9 mm Hg) for the combined intervention group; patterns were similar for diastolic BP. LIMITATION: Changes in medication use and diet were monitored only in intervention participants; 24-month outcome data were missing for 25% of participants, BP control was adequate at baseline in 73% of participants, and the study setting was an academic health center.

conclusionCombined home BP monitoring and tailored behavioral telephone intervention improved BP control, systolic BP, and diastolic BP at 24 months relative to usual care. .
