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 study mainly explored the potential mechanism of Huangqi Guizhi Wuwu Decoction (HGWD) in the treatment of osteoarthritis (OA) based on network pharmacology, and to investigate whether HGWD promotes osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) by upregulating ESR1 based on in vitro experiments. The core target genes and potential signaling pathways related to HGWD in OA treatment were analyzed using network pharmacology analysis. BMSCs were isolated from rats to induce for adipogenic/osteogenic differentiation, which were assessed by Oil Red O staining and Alizarin Red staining, respectively. ESR1 knockdown lentivirus was transfected into BMSCs and different concentrations of rat HGWD-containing serum was prepared to treat BMSCs. Cell proliferation activity was measured by CCK-8 assay to select the optimal concentration for further experiments. Cells were treated with 10% HGWD-containing serum and transfected with ESR1 knockdown lentivirus. Osteogenic differentiation was assessed by ALP staining, ALP activity measurement, and Alizarin Red staining. The expression of osteogenic differentiation-related genes OCN, RUNX2, and COL1A1 was detected by qRT-PCR and Western blot. Network pharmacology analysis revealed that ESR1 is one of the core targets of HGWD in OA treatment. HGWD-containing serum promoted proliferation and osteogenic differentiation ability of BMSCs, and also increased ESR1 expression. The promoting effects of HGWD-containing serum on proliferation and osteogenic differentiation were partially polished in response to ESR1 knockdown in BMSCs. Based on the collective evidence, the therapeutic effects of HGWD in OA may be achieved by promoting osteogenic differentiation of BMSCs via upregulating ESR1 expression.
