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

An age-related decline in endocannabinoid system (ECS) activity may contribute to conditions such as chronic pain and Alzheimer's disease. Although cannabis is increasingly used by older adults to alleviate age-related conditions, it remains unclear how cannabinoids affect ECS activity across the lifespan. The present study assayed levels of seven endocannabinoids (AEA, 2-AG, DEA, LEA, PEA, SEA, and OEA) in a sample of adults (N = 142; younger 21-24 years, n = 38; midlife 25-54, n = 73; older 55-71, n = 31) assayed before cannabis use (baseline [pre-use]) and ~ 1 h after flower or ~ 2 h after edible cannabis use. At baseline, older adults exhibited lower AEA and DEA than younger adults, and lower LEA than midlife adults. Acute cannabis use increased AEA, DEA, LEA, PEA, SEA, and OEA across all age groups (all p < .001). 2-AG showed no increase. For AEA and DEA, increases were larger in older adults (Time×Age). These findings indicate broad endocannabinoid elevations after cannabis use regardless of age, alongside age-related differences at baseline and in acute responses.
