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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundDietary Approaches to Stop Hypertension (DASH) is a recommended first-line treatment for adults with hypertension, yet adherence to DASH is low. To evaluate the efficacy of a digital health intervention (DHI), compared with attention control, on changes in DASH adherence and blood pressure among adults with hypertension.

methodsNourish was a 12-month, parallel, 2-arm, randomized controlled trial of a virtually delivered DHI. Participants had a previous diagnosis of hypertension. The primary outcome was a 6-month change in DASH adherence. The secondary outcome was a change in blood pressure. We used linear mixed models to compare 6 and 12-month changes in DASH adherence, systolic blood pressure, and diastolic blood pressure.

resultsNourish randomized 301 adults who averaged 54.4 (SD, 13.4) years and predominately identified as female (65%), White (53%), or Black (31%). Adjusted mean baseline DASH score was 2.30 (95% CI, 2.03-2.58). The adjusted mean baseline systolic blood pressure and diastolic blood pressure were 123.2 (95% CI, 119.5-126.9) and 77.1 (95% CI, 74.6-79.6) mm Hg. DASH score change was not significantly different between arms at 6 months (

conclusionsA DHI led to modest improvements in DASH and blood pressure among adults with hypertension but did not outperform the attention control. Further research is needed to understand the utility of DHIs to promote DASH and identify intervention components that support long-term behavior change.
