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
The objective of this study was to extract and characterize nanocellulose from sesame husks, which are typically discarded as waste by sesame processing facilities. However, these husks are rich in cellulose, presenting a valuable potential source for nanocellulose. Sesame husk cellulose (SHC) was initially isolated through a multi-step process that removed oil, hemicellulose, and lignin. Sesame husk nanocellulose (SHNC) was subsequently obtained via acid hydrolysis. Energy-dispersive X-ray (EDX) analysis revealed a purity of 99.32 % for SHNC. The yields of SHC and SHNC were 25.16 % and 9.17 %, respectively. SHNC exhibited a lower surface charge (-27.2 mV) compared to SHC (-15.5 mV). FTIR confirmed the presence of characteristic cellulose bands. Dynamic light scattering (DLS) revealed average particle diameters of 2235 nm for SHC and 108.1 nm for SHNC. Atomic force microscopy (AFM) and field-emission scanning electron microscopy (FE-SEM) analyses showed that SHNC particles were spherical to oval-shaped, with average diameters of 78.41 nm and 74.30 nm, respectively. The crystallinity index was higher for SHNC (67.74 %) compared to SHC (41.02 %). Thermogravimetric analysis (TGA) indicated greater thermal stability for SHC (TMax 317 °C) compared to SHNC (TMax 287 °C). These results demonstrate the potential of sesame husks as a sustainable and valuable source of nanocellulose.
