Evaluation of Surface Roughness, Color Stability, and FTIR Characterization of Different Inorganic-Filled PEEK Materials After Coffee Thermal Cycling.

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
Inorganic fillers are incorporated into polyetheretherketone (PEEK) to enhance mechanical performance, yet their long-term stability in chromogenic media remains insufficiently explored. This study evaluated the color stability, surface roughness, and chemical changes in modified PEEK variants following coffee thermal cycling. In this study, four PEEK materials were tested: unfilled (P), glass fiber-reinforced (GFP), nanoceramic-filled (CR), and titanium dioxide-filled (TP). A total of 40 disk-shaped specimens (10 × 2 mm,
