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
Aim of the study: This study aims to evaluate and compare the stress distribution patterns of two experimental tissue-level, convergent collar implants (one made of Ti-6Al-4V (control) and the other of Roxolid-based (Ti-15Zr) material) using 3D finite element analysis (FEA) under various simulated masticatory conditions. Methods: A 3D finite element model replicating a tissue-level implant with convergent neck design was developed in ANSYS software, incorporating both cortical and trabecular bone geometry. Implants made of Ti-6Al-4V-Grade 5 and Roxolide-type-Ti-15Zr alloy were simulated under axial (0°) and oblique (45° angle) loading forces (50 N, 200 N, 300 N, and 400 N). The von Mises equivalent stress distribution was calculated to assess the biomechanical performance. Results: Under masticatory forces simulation, titanium-alloy implants exhibited maximum stress values (400 N) of 260.38 MPa under axial load and 536.2 MPa under oblique load. Ti-15Zr implants exhibited a slightly lower peak stress of 506.95 MPa under a load of 400 N at a 45° inclination and 240.81 N under axial load. Based on 3D finite analysis, the stress distribution maps showed higher concentration in the implant-abutment connection and the cervical region, particularly under oblique loading. Conclusions: Although titanium implants exhibited higher stress limits, Ti-15Zr implants showed biomechanical stability under oblique simulated forces. Ti-15Zr implants exhibited a more uniform stress distribution with a reduced peak concentration.
