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
Hip replacement is a widespread surgical procedure that eliminates pain and restores motor functions of the pathologically altered hip joint. The issue lies in the lack of pre-operative strength calculations for implant shapes. So, they tend to break after surgery or damage the bone due to the complex stress-strain state. In the present paper, we studied the stress-strain state and ultimate load of S-type canine femoral implants based on titanium alloy Ti6Al4V using finite element analysis for static and cyclic loads. X-ray computed micro tomography data were used to construct the models. Re-engineering and restoration of the 3D geometry of the product were conducted. Strength analysis was performed in the finite element analysis software package Ansys Mechanical was used for various types of implant support. Locations with stress concentrators were identified, and ultimate loads on the implant were obtained. The influence of the rigidity of the support on the prosthesis stem was also studied. For the case of rigid support, the stress-strain state of the prosthesis was studied and the ultimate load was found to be 30.1 kg.
