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: This study aimed to evaluate the influence of autoclave sterilization on the cyclic fatigue resistance of nickel-titanium (NiTi) endodontic files with different NiTi alloy treatments. Materials and Methodology: The research examined Hyflex CM, Bassi Logic, TruNatomy, and ProTaper Gold files, which were divided into control, conventional sterilization, and flash sterilization groups. Poststerilization, the instruments were tested using a custom-made Dynamic Cyclic Fatigue Testing Device replicating root canal procedures. Group 1 used HyFlex CM (size 25, taper 0.04), Group 2 used Bassi Logic (size 25, taper 0.04), Group 3 used TruNatomy (size 25, taper 0.04), and Group 4 used ProTaper Gold (size F1). After rotating each instrument until it fractured, the number of cycles to failure was determined and the time to fracture was noted. Statistical Analysis: Statistical analysis was conducted using SPSS 26.0 (Statistical software developed by IBM) with one-way ANOVA and Tukey honestly significant difference Results: HyFlex CM had the highest fracture resistance, whereas ProTaper Gold had the lowest. Sterilization increased the cyclic fatigue resistance of HyFlex CM, Bassi Logic, and ProTaper Gold but decreased that of TruNatomy. Conclusion: The study concluded that sterilization enhances cyclic fatigue resistance, except for TruNatomy files, and emphasized understanding NiTi alloy properties to mitigate instrument failure.
