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

This review summarizes the literature on the association between tea consumption and cognitive health in late life. Population-based studies reviewed in this article suggest that tea drinking has beneficial effects on cognitive function of elderly persons. However, a cause-effect relationship between tea consumption and cognitive decline and dementia could not be drawn given inconsistent findings from only two longitudinal cohort studies. The neuroprotective effects of tea consumption could be due to catechins, L-theanine and other compounds in tea leaves. More longitudinal observational study is needed. Information on life-time tea consumption and blood concentrations of catechins and L-theanine could be collected in future studies.
