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

backgroundAccumulating evidence suggests that Ginkgo biloba is cardioprotective, in part, through its vasodilatory and antihypertensive properties. However, definitive data on its blood pressure (BP)-lowering effects in humans is lacking.

methodsWe determined the effects of G. biloba extract (240 mg/day) on BP and incident hypertension in 3,069 participants (mean age, 79 years; 46% female; 96% white) from the Ginkgo Evaluation of Memory (GEM) study. We also examined whether the treatment effects are modified by baseline hypertension status.

resultsAt baseline, 54% of the study participants were hypertensive, 28% were prehypertensive, and 17% were normotensive. Over a median follow-up of 6.1 years, there were similar changes in BP and pulse pressure (PP) in the G. biloba and placebo groups. Although baseline hypertension status did not modify the antihypertensive effects of G. biloba, it did influence the changes in BP variables observed during follow-up, with decreases in hypertensives, increases in normotensives, and no changes in prehypertensives. Among participants who were not on antihypertensive medications at baseline, there was no difference between treatment groups in medication use over time, as the odds ratio (95% confidence interval (CI)) for being a never-user in the G. biloba group was 0.75 (0.48-1.16). The rate of incident hypertension also did not differ between participants assigned to G. biloba vs. placebo (hazard ratio (HR), 0.99, 95% CI, 0.84-1.15).

conclusionsOur data indicate that G. biloba does not reduce BP or the incidence of hypertension in elderly men and women.
