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

backgroundTear trough deformity is a prominent periorbital aging manifestation, and minimally invasive filler injection has become a preferred alternative to surgical correction. However, the optimal mixing ratio of collagen (Col) and hyaluronic acid (HA) fillers, as well as refined injection techniques for the delicate infraorbital region, remains a further in-depth investigation.

objectiveTo screen the optimal volume ratio of collagen-HA mixed fillers, verify its anti-photoaging mechanism, and evaluate its clinical efficacy and safety for infraorbital rejuvenation.

methodsA multi-modal study was conducted, the in vitro experiments including cell viability, ROS detection, and ELISA assay for effect of the mix fillers on UV-induced photoaged human dermal fibroblasts (HDFs), as well as the injection forces of the mix fillers. The in vivo study was conducted on UV-induced photoaging mice model with histological, immunofluorescence, and ELISA detections. Additionally, a prospective randomized controlled clinical trial combined with an innovative injection technique was performed to further verify the efficacy and safety of the mix fillers.

resultsIn vitro, the Col/HA (2:1) mix filler treated group showed the highest cell viability, most significant ROS reduction, and strongest collagen synthesis promotion. In vivo, this mix filler effectively alleviated UV-induced skin photoaging, restored collagen and elastic fiber structure and content, suppressed cellular senescence and inflammation. In clinical practice, this mix filler treated group maintained the highest AIHS improvement rate and optimal GAIS scores at 6 months, with the lowest incidence of postoperative complications, such as Tyndall phenomenon, and lumpiness. The other two mix filler (Col/HA(1:1) and Col/HA(1:2)) treated groups exhibited inferior efficacy and safety.

conclusionThe Col/HA (2:1) mix filler, combined with the innovative short fine needle vertical layered injection technique, exhibits excellent anti-photoaging effects and safety, providing a standardized and refined clinical strategy for minimally invasive infraorbital rejuvenation.
