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

introductionHypertension is a progressive cardiovascular condition arising from complex aetiologies. Progression is strongly associated with functional and structural abnormalities that lead to multi-organ dysfunction. Stroke and myocardial infarction are two of the major complications of hypertension in India. Various anti-hypertensive drugs, such as calcium channel blockers (CCBs), beta-blockers, diuretics, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, have been the medications of choice for disease management and are known to be effective in reducing the complications of hypertension. CCBs, such as amlodipine, are also currently being used and proven to be effective, although their beneficial effects in the management of complications of hypertension like stroke and myocardial infarction (MI) have yet to be proven. Therefore, the aim of this systematic review was to evaluate the effect of amlodipine on stroke and MI in hypertensive patients.

methodsA systematic search of English electronic databases was performed for studies with sufficient statistical power that were published between 2000 andl 30 August 2020, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. A total of 676 papers were screened, and 13 were found eligible to be included in the meta-analysis. Studies that included patients who suffered from MI or stroke and were under amlodipine treatment were included in the analysis. The odds ratio and the risk ratio of amlodipine compared to active control/placebo were noted from the studies and statistically analyzed.

resultsAmlodipine had a significant effect in reducing stroke and MI in hypertensive patients. Similar to results published in reports, this systematic review proved that the hazard ratio for amlodipine was < 1 for stroke (0.69-1.04) and MI (0.77-0.98), showing that amlodipine accounted for better prevention of stroke and MI.

conclusionIn the pooled analysis of data from 12 randomised controlled trials and one double-blinded cohort study measuring the effect of CCBs, we found that the CCB amlodipine reduced the risk of stroke and MI in hypertensive patients. Superior results for amlodipine were found in ten of the 13 studies included in this meta-analysis.
