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
Shrinkage consideration is pivotal in modeling heat and mass transfer during drying processes. This study investigated the interactive effects of microwave power and pulse ratio on various properties of potato slices during drying. The drying process was further modeled using moving boundary conditions to assess the influence of these variables on heat and moisture diffusion. Results demonstrated that increasing microwave power and decreasing the pulse ratio significantly reduced drying time due to intensified effective moisture diffusion coefficient (14.28%). Enhanced product quality-evidenced by minimized shrinkage (26.28%), reduced bulk density (13.22%), and improved rehydration ratio (28.96%)-alongside increased energy efficiency, was observed with higher power levels and pulse ratios. Additionally, a higher pulse ratio intensified the electric field due to shorter microwave "on" durations, promoting a more uniform wave distribution within the product. Unlike convective air drying, where moisture removal initiated from the food's edges, the combined microwave-air drying approach exhibited a distinct moisture migration pattern attributed to the volumetric heating mechanism of microwaves, which directed heat transfer from the interior to the surface of the potato slices. The model's performance, evaluated using R
