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
Introduction: This study aimed to optimize the process parameters for developing nutritionally enriched biscuits incorporating Methods: A Box-Behnken design was employed to evaluate the effects of MOLP percentage (10-30%), baking temperature (170-200°C), and baking time (10-14 min) on six critical responses: spread ratio, colour index, hardness, water activity, baking weight loss, and overall sensory acceptability. In addition to RSM-based numerical optimisation, the Grey Wolf Optimisation (GWO) algorithm was used to further optimise the polynomial models generated by RSM, enabling a robust metaheuristic search for global optima and enhancing the reliability of the optimised process conditions. Results: Numerical optimization yielded an ideal formulation comprising 10% MOLP, 30% jackfruit seed powder, a baking temperature of 193.68°C, and a baking time of 13.97 minutes. The optimized biscuit exhibited a spread ratio of 6.22, colour index of 161.68, hardness of 2500.58 g, water activity of 0.66, baking weight loss of 7.23%, and overall acceptability score of 7.95, with a desirability of 0.828. Discussion: Validation trials showed strong agreement between predicted and experimental values for most responses (
