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
Percutaneous collagen induction (PCI) is an alternative treatment for skin dysfunctions, it aims to stimulate collagen production by encouraging normal wound healing that occurs after any trauma by inducing microlesions; also it may be potentiated with the association with drugs such as hyaluronic acid (HA). Our objective was to evaluate the effects of PCI associated with hyaluronic acid (0.9%) on inflammatory process, oxidative stress, and collagen production in rat epidermis. For the study, 36 adult Wistar rats were randomly divided into 6 groups (n = 6): Control; PCI 0.5; PCI 1.0; HA; PCI 0.5 + HA; and PCI 1.0 + HA. The animals were anesthetized, trichotomized, and the application of therapies was performed once; After 7 days, the animals were euthanized for removal of the skin region. Levels of pro-inflammatory (IL1, IL6, TNFα), anti-inflammatory (IL4 and IL10) cytokines and growth factors (FGF, TGFβ) were evaluated, besides oxidative stress parameters and histological analysis. In combination groups, there is a decrease in TNFα compared with the control and PCI groups in contrast to a significant increase in anti-inflammatory cytokines and growth factors. Oxidant and oxidative damage levels showed a significant decrease in PCI + HA groups in relation to PCI groups while antioxidant defense increased in PCI + HA groups compared with the control group. The number of fibroblasts was increased in the PCI 1.0 group in relation to the control, HA, and PCI 0.5. The number of blood vessels and collagen area was increased in groups PCI and PCI + HA compared with the HA group. We conclude that the combination of PCI with HA is able to accelerate the acute inflammatory process, reducing its deleterious effects and anticipating the chronic response, contributing to tissue repair.
