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

Metabolic syndrome (MetS) is associated with reduced nitric oxide (NO) bioavailability and impaired cerebrovascular function, potentially increasing cognitive decline risk. Dynamic cerebral autoregulation (dCA) maintains cerebral blood flow and may involve NO-related vascular mechanisms. Whether dietary nitrate supplementation influences dCA in MetS remains unclear. This pilot trial evaluated feasibility and explored effects of nitrate supplementation on dCA. Twenty-two older adults with MetS (55-75 years) were randomized in a double-blind, placebo-controlled design to receive nitrate-rich beetroot juice (BRJ; 6.4 mmol NO
