Research on features selection of medical diagnostic models based on L-S-ACO algorithm.
Article in iScience, 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
Feature selection for medical diagnostic models must account for feature interdependencies rather than independence. Ant colony optimization (ACO), a heuristic algorithm inspired by ant foraging, effectively addresses feature selection and correlation challenges. Published studies show that integrating ACO with other algorithms and refining pheromone-heuristic computations significantly boosts medical data feature selection performance. To tackle the issue of features correlation in medical diagnostic models, this study presents the L-S-ACO algorithm by combining the ACO algorithm with two additional algorithms: Light gradient boosting machine (LightGBM) and stochastic average gradient (SAG). Based on this algorithm, a medical diagnostic model is developed, and its practical application in disease diagnosis is analyzed. The analysis results demonstrate that the proposed algorithm improves accuracy (ACC) by 5.81%, F1 score by 6.21%, area under the curve (AUC) by 4.08%, precision by 5.12%, and recall by 6.35%.
