Effects of a Combination of Water-Soluble CoenzymeQ10 and Collagen on Skin Parameters and Condition:Results of a Randomised, Placebo-Controlled,Double-Blind Study.
Trial report in Nutrients, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers, 3 of them syntheses that pooled 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.
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
Skin is a complex and dynamic organ that provides a protective interface between theexternal environment and the body; changes in skin appearance are often the first visible signs ofaging. It is well established that nutrients and other bioactive substances have important roles in thestructure and functions of human skin; however, the effects of dietary supplementation of suchbioactives are much less investigated. The objective of this randomised, double-blind placebocontrolledstudy was to investigate the effects of liquid food supplement, characterised by acombination of water-soluble coenzyme Q10 (Q10Vital®) and collagen, on dermal density and otherskin parameters in comparison to placebo. The trial was performed on 34 healthy women aged 40-65 that received either the test product (
