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

objectivesTo investigate the effect of polymorphisms in renin angiotensin system genes on the association between angiotensin-converting enzyme inhibitor (ACEI) exposure and global and executive cognitive function in the Health, Aging and Body Composition study.

designCohort study.

settingCommunity.

participantsThree thousand seventy-five participants: mean age 73.6, 58% Caucasian, 52% female, 15% taking ACE-Is, 8 years of follow-up. MEASUREMENTS: The outcomes were longitudinal change in Executive Clock Drawing Test-1 (CLOX1), the Digit Symbol Substitution test, and the Modified Mini-Mental State Examination. The genetic polymorphisms included angiotensin-converting enzyme insertion deletion (ACEID) in the ACE gene and the M235T and 6AG polymorphisms in the angiotensinogen (AGT) gene.

resultsFor the CLOX1 outcome, there was significant interaction between 6AG and M235T polymorphisms in the AGT gene and angiotensin-converting enzyme inhibitors (ACE-Is) in Caucasian participants (P=.01 for both polymorphisms) independent of blood pressure levels. Specifically, ACE-I exposure was protective against CLOX1 score decline in carriers of the AA genotype of the 6AG and the CC genotype of the M235T (for the ACE-I vs non-ACE-I groups, P=.01 for 6AG and P=.005 for M235T) but not the other genotypes. These associations were not significant with other cognitive tests, with ACEID, or in African Americans.

conclusionACE-Is may provide a protective effect on executive function in Caucasians with AGT gene polymorphisms known to be associated with greater renin angiotensin system activity. If confirmed in a pharmacogenetic trial, ACE-Is may be found to have additional cognitive protection in a select group of elderly individuals.
