Diagnosing hypertension in Indigenous Canadians (DREAM-GLOBAL): A randomized controlled trial to compare the effectiveness of short message service messaging for management of hypertension: Main results.
Trial report in Journal of clinical hypertension (Greenwich, Conn.), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 papers, 3 of them syntheses that pooled 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.
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
Hypertension, the leading cause of cardiovascular morbidity and mortality, affects more than 1 billion people globally. The rise in mobile health in particular the use of mobile phones and short message service (SMS) to support disease management provides an opportunity to improve hypertension awareness, treatment, and control, in remote and vulnerable patient populations. The primary objective of this randomized controlled study was to assess the effect of active (with hypertension specific management SMS) or passive (health behaviors SMS alone) on the difference in blood pressure (BP) reduction between the active and passive SMS groups in hypertensive Canadian First Nations people from six rural and remote communities. Pragmatic features of the study included shifting of BP measures to non-medical health workers. Despite an overall reduction in BP over the study, there was no difference in the BP change between groups from baseline to final for systolic 0.8 (95% CI -4.2 to 5.8 mm Hg) or diastolic -1.0 (95% CI -3.7 to 1.8 mm Hg, P = 0.5) BP. Achieved BP control was 37.5% (25.6%-49.4%, 95% CI) in the active group and 32.8% (20.6%-44.8%, 95% CI) in the passive group (difference in proportions -4.74% (-21.7% to 12.2%, 95% CI, P = 0.6). The study looked at changes in health services delivery, mobile health technologies, and patient engagement to support better management of hypertension in Canadian First Nations communities. The active hypertension specific SMS did not lead to improvements in BP control.
