Trial report in Lipids, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02211417 (A Randomised, Double-Blind, Placebo-Controlled, Phase II Study to Assess the Efficacy and Safety of Orally Administered DS107G to Patients With Moderate to Severe Atopic Dermatitis), which is not on this map.

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.

Abstract

Dihomo-γ-linolenic acid (DGLA) is one of the polyunsaturated fatty acids, and is expected to show anti-allergic activity. We examined the effects of supplementation with DGLA-enriched oil (450 mg as free DGLA) for 4 weeks in healthy adults in a randomized controlled study. The DGLA composition in the total fatty acids of serum phospholipids increased from 2.0 to 3.4%, and returned to the initial level after a 4-week washout. No side effects or changes in blood biochemical parameters were observed. These results indicate that serum DGLA content can be safely increased by supplementation with 450 mg DGLA under these conditions.
