Effect of a Multicomponent Intervention on Antihypertensive Medication Intensification in Rural South Asia: Post Hoc Analysis of a Cluster RCT.
Trial report in American journal of hypertension, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02657746 (Control of Blood Pressure and Risk Attenuation-Bangladesh, Pakistan and Sri Lanka), which is not on this map. Not yet cited in PubMed.
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
backgroundInadequate treatment of hypertension is a widespread problem, especially in South Asian countries where cardiovascular disease mortality rates are high. We aimed to explore the effect of a multicomponent intervention (MCI) on antihypertensive medication intensification among rural South Asians with hypertension.
methodsA post hoc analysis of a 2-year cluster-randomized controlled trial including 2,645 hypertensives aged ≥40 years from 30 rural communities, 10 each, in Bangladesh, Pakistan, and Sri Lanka. Independent assessors collected information on participants' self-reports and physical inspection of medications. The main outcomes were the changes from baseline to 24 months in the following: (i) the therapeutic intensity score (TIS) for all (and class-specific) antihypertensive medications; (ii) the number of antihypertensive medications in all trial participants.
resultsAt 24 months, the mean increase in the TIS score of all antihypertensive medications was 0.11 in the MCI group and 0.03 in the control group, with a between-group difference in the increase of 0.08 (95% confidence interval (CI, 0.03, 0.12); P = 0.002). In MCI compared with controls, a greater increase in the TIS of renin-angiotensin-aldosterone system blockers (0.05; 95% CI (0.02, 0.07); P < 0.001) and calcium channel blockers (0.03; 95% CI (0.00, 0.05); P = 0.031), and in the number of antihypertensive medications (0.11, 95% CI (0.02, 0.19); P = 0.016) was observed.
conclusionsIn rural communities in Bangladesh, Pakistan, and Sri Lanka, MCI led to a greater increase in antihypertensive medication intensification compared with the usual care among adults with hypertension. CLINICAL TRIALS REGISTRATION: Trial Number NCT02657746.
