Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
This investigation presents a novel approach to engineering mesoporous bioactive glass nanoparticles (MBGNs) through selective ion doping. This method can significantly potentiate their physicochemical properties and biological performance. We elucidate the effects of boron (B) and cobalt (Co) doping, individually and in combination, on MBGNs' structural, functional, and biocompatible characteristics. Using microemulsion-assisted sol-gel synthesis, we fabricated MBGNs with sizes ranging from 150 to 250 nm and shapes that shifted from spherical to more irregular shapes upon co-doping, as observed by SEM and TEM. We assessed the materials' amorphous nature and molecular structure through XRD and FTIR, respectively, noting the preservation of bioactivity-associated Si-O-Si groups. This can influence the nucleation and growth of the mineral phases similar to those found in natural tissues, forming a bioactive coating on the material surface. Nitrogen adsorption-desorption isotherms confirmed a mesoporous structure with increased specific surface area upon co-doping. The release behavior of Ca and Si in simulated body fluids studied by ICP-OES indicated alterations after adding Co and B, modifying their release kinetics. Bone regeneration relies on osteogenesis and vascular network formation for nutrient and oxygen supply. This study highlights the synergistic effect of B and Co co-doping, enhancing both angiogenesis and osteogenesis beyond single-ion doping. Biocompatibility studies with MG-63 and HDFa cell lines indicated that B enhanced cell viability, while the viability effect of Co was concentration-dependent. Cytotoxicity was assessed through lactate dehydrogenase (LDH) assays and is shown in high concentrations in the case of reference and B-doped sample, which was significantly reduced in the case of co-doped material. The newly developed nanoparticles showed a 10-fold increase in vascular endothelial growth factor (VEGF) secretion compared to the control sample (
