RF-SVR-based prediction methodology for metal tube-bending rebound: Handling non-uniformity and limited sample challenges.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This paper explores a prediction algorithm for determining the rebound angle of non-uniform and small-sample tubes. To address the issues of non-uniform and small-sample data, this paper proposes an algorithm based on Random Forest-Support Vector Regression (RF-SVR). Firstly, the polynomial feature generation method is introduced to solve the problem of non-uniform data. Secondly, after obtaining the data generated by the polynomial features, RF (Random Forest, an algorithm based on classification trees) is introduced to select the rebound features of the tubes, so that the features that have a profound influence on the rebound Angle can be retained. After obtaining the new data set, SVR (Support Vector Regression, an algorithm specifically designed for solving regression problems) is used to predict the rebound model of the bending of the metal tubes. The experimental results show that the RF-SVR method is superior to the traditional RF-BP and SVR methods, achieving higher prediction accuracy on small samples and non-uniform datasets.
