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
Reconstituted tobacco leaves (RTLs) are widely used in heat-not-burn products, but single-component binders can limit their sheet integrity and sensory quality. Here, carboxymethyl fenugreek polysaccharide (CFP) was blended with sodium carboxymethyl cellulose (CMC) at CFP : CMC mass ratios of 0 : 10, 1 : 9, 3 : 7, 5 : 5 and 10 : 0 and evaluated in thick-slurry RTLs. The viscosity, FT-IR spectra, moisture behaviour, contact angle, SEM morphology, tensile and tear properties, thermal behaviour, pyrolysis products, smoke volume and sensory quality were analyzed. The 5 : 5 blend showed the highest adhesive viscosity (912 cP at 1 wt% and 25 °C). Relative to CMC alone, the 5 : 5 blend increased the tensile strength by 11.9%, tear index by 8.74% and bulk specific volume by 9.93%, while the softness value decreased by 26.45% and the sensory score increased from 71.0 to 77.2. Contact angle and moisture measurements indicated reduced hygroscopicity and improved moisture retention. TGA showed comparable thermal degradation profiles, while Py-GC/MS detected 85 products for the 5 : 5 blend compared with 48 for CMC alone. The smoke volume changed only modestly across the puff sequence. These results support CFP/CMC blending as a promising formulation strategy for improving the physical and sensory performance of thick-slurry RTLs.
