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
backgroundRosavin, a bioactive compound derived from Rhodiola rosea, has been proposed to modulate osteoblast-associated signaling pathways. Emerging evidence highlights the role of CX3CL1 (fractalkine) in bone-immune interactions. This study aimed to investigate whether rosavin modulates CX3CL1 secretion and osteoblast morphology and confluence in human osteoblasts (HOB) in vitro, thereby providing descriptive cellular evidence relevant to CX3CL1-associated osteoblast responses under mineralizing conditions.
methodsPrior to biological testing, the chemical identity of rosavin was verified by high-resolution electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-QTOF-MS). HOB were cultured in growth medium (DMEM-g), mineralization medium (DMEM-m), or DMEM-m supplemented with rosavin at 50 µM (R50) or 100 µM (R100). Cell morphology and confluence were assessed by phase-contrast microscopy, supported by semi-quantitative image-based estimation of cell-covered area using Fiji/ImageJ. Sirius Red staining was performed only in the DMEM-m mineralization control group and was evaluated qualitatively as a supportive assessment of extracellular matrix maturation.
resultsRosavin was associated with dose- and time-dependent changes in CX3CL1 secretion and morphology-related observations in HOB cultures. The 50 µM rosavin condition showed significantly increased CX3CL1 secretion at days 14 and 21 compared with DMEM-m alone and was associated with higher cell confluence and predominance of cuboidal cell morphology. In contrast, the 100 µM condition was associated with lower apparent confluence, mixed cellular morphology, and reduced CX3CL1 secretion at later time points.
conclusionsThese observations are descriptive, preliminary, and hypothesis-generating. Rosavin was associated with concentration-dependent modulation of CX3CL1 secretion and osteoblast morphological characteristics in vitro; however, the biological significance of CX3CL1 modulation in this monoculture model remains uncertain. Further mechanistic and functional studies are required.
