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
Introduction: and aim: Due to its excellent mechanical strength and biocompatibility, Polyetherketoneketone (PEKK) is emerging as a potential substitute for titanium in dental implant applications. The aim of the study was to evaluate its cytotoxicity, pro-inflammatory responses, and molecular interactions to assess its potential in implant applications. Methods: This study evaluated the cytotoxicity, pro-inflammatory cytokine responses, and molecular interactions of PEKK compared to titanium. Disc-shaped samples (10 mm × 2 mm) were fabricated for each material following ISO standards. Human periodontal fibroblast cells were cultured and treated with the samples for cytotoxicity assessment using the MTT assay, while pro-inflammatory cytokine gene expression (IL-1β, TNF-α) was analyzed via real-time PCR. Molecular docking was conducted using AutoDock to investigate PEKK's binding interactions with cytokines, and data was analyzed with one-way ANOVA and post hoc test (P < 0.05). Results: PEKK showed comparable cytocompatibility to titanium, yielding similar outcomes in cell viability (P > 0.05) or pro-inflammatory cytokine expression (P > 0.05). Molecular docking revealed strong interactions with IL-1β (-8.9 kcal/mol) and TNF-α (-7.3 kcal/mol). Conclusion: This study demonstrates that PEKK exhibits comparable cytocompatibility and pro-inflammatory responses to titanium, with a potential to modulate inflammatory pathways. Further in vivo studies are needed to confirm its clinical viability as an implant material. Clinical relevance: This study gives the clue of PEKK as an aesthetic implant biomaterial and it can be useful as an alternative to Titanium dental implant.
