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
Additive manufacturing utilizes various reactive precursors to fabricate diverse products, including prototypes, functional components, and designer objects. This work presents a synthesis approach toward a novel biobased printable compound, 2-hydroxypropyl ricinoleate dimethacrylate (2-HPRDM). Our proposed strategy involves the castor oil transesterification process, producing 2-hydroxypropyl ricinoleate (2-HPR). We used high-performance liquid chromatography (HPLC) analysis to investigate the reaction progress at equimolar and excess reactant concentrations. This fatty acid ester was modified with methacrylic anhydride to form 2-HPRDM, releasing the secondary reaction product methacrylic acid (MA). This compound was used for the synthesis of propylene glycol dimethacrylate (PGDMA), which valorized all potential wastes generated during the 2-HPRDM production. This article presents the innovative vacuum-distillation esterification approach that generates PGDMA. All synthesized compounds were structurally characterized via NMR, ESI-MS, and FTIR analyses. The formed curable compounds were fabricated into testing specimens and a detailed prototype by an mSLA three-dimensional (3D) printer to confirm their usability. The 3D-printed object was used for the mechanical and thermomechanical characterization of the formulated curable resins via dynamic mechanical analysis (DMA), tensile, and flexural tests. The best-performing 2-HPRDM-based system contained 45 wt % of PGDMA and recorded a storage modulus of 750 MPa, a glass-transition temperature of 85.6 °C, a cross-linking density of 18.9 kmol/m
