Optimized machine learning and artificial neural networks for NIRS-based prediction of mango internal quality.
Article in Scientific reports, 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
A robust and updated approach for non-destructive prediction of key quality attributes in intact mangoes was developed by integrating near-infrared reflectance spectroscopy (NIRS) with advanced machine learning and artificial neural network (ANN) algorithms. In this study, NIR spectral data of 136 mango samples were collected and processed using standard normal variate (SNV) correction. Five regression methods namely partial least squares regression (PLSR), support vector machine regression (SVMR), random forest regression (RFR), extreme gradient boosting (XG-Boost), and generalized regression neural network (GRNN), were optimized and evaluated for predicting total acidity (TA) and ascorbic acid (AA). Results indicate that while traditional linear methods like PLSR achieved reasonable predictive power (RPD > 2.5), nonlinear models, especially XGBoost and GRNN, significantly outperformed PLSR, with GRNN models achieving the highest accuracy, with maximum performance reaching R
