Red palm olein supplementation on cytokines, endothelial function and lipid profile in centrally overweight individuals: a randomised controlled trial.
Trial report in European journal of clinical nutrition, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
BACKGROUND/
objectivesThe consumption of antioxidant-rich cooking oil such as red palm olein may be cardioprotective from the perspective of subclinical inflammation and endothelial function. SUBJECTS/
methodsUsing a crossover design, we conducted a randomised controlled trial in 53 free-living high-risk abdominally overweight subjects, comparing the effects of incorporating red palm olein (with palm olein as control) in a supervised isocaloric 2100 kcal diet of 30% en fat, two-thirds (45 g/day) of which were derived from the test oil for a period of 6 weeks each.
resultsWe did not observe a significant change in interleukin-6 (IL-6), in parallel with other pro-inflammatory (tumour necrosis factor-β, interleukin-1β, IL-1β, high sensitivity C-reactive protein, hsCRP) and endothelial function (soluble intercellular adhesion molecules, sICAM, soluble intravascular adhesion molecules, sVCAM) parameters. Interestingly, we observed a significant reduction in oxidised LDL levels (P < 0.0386) while on the red palm olein diet, together with the increase in plasma alpha tocopherol (P < 0.0002), alpha carotene (P < 0.0001) and beta carotene (P < 0.0001) concentrations compared with palm olein diet.
conclusionRed palm olein did not improve subclinical inflammation and endothelial function despite profound increase in antioxidant levels. The positive improvement in oxidised LDL merits further attention in this group of subjects at risk of developing cardiovascular disease.
