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
OBJECTIVE AND
designBiochanin A (BCA), a phytoestrogen, has various pharmacological properties. This study was conducted to compare BCA's therapeutic property against 17-β estradiol replacement therapy in zymosan-induced arthritis (ZIA) in mice. Additionally, we further investigated in vitro the anti-inflammatory action on neutrophils. TREATMENT: Ovariectomized (OVX) and non-OVX mice were pretreated with BCA (1, 3 and 9 mg/kg) or estrogen (50 µg/kg) for 14 days prior to ZIA. Neutrophils were pretreated with BCA (1, 10 and 100 μM) for 1 h prior to phorbol 12-myristate 13-acetate.
methodsAnti-inflammatory effects of BCA were evaluated by cellular infiltrate, paw edema and cytokine measurement. In vitro, apoptosis was assessed by morphology and flow cytometry. Neutrophil extracellular traps (NET) were determined by fluorescent microscopy and DNA release. Statistical differences were determined by one- or two-way ANOVA.
resultsBCA inhibited neutrophil accumulation, paw edema and proinflammatory cytokine (TNF-α and IFN-γ) and increased anti-inflammatory cytokines (IL-4 and IL-10) in OVX and non-OVX mice, similar to 17-β estradiol replacement therapy. In vitro, BCA increased apoptosis and consequently reduced NETs.
conclusionBCA has a notable anti-inflammatory effect, similar to 17-β estradiol, and is especially effective for treatment of ZIA. These results suggest that BCA may be promising for the treatment of postmenopausal arthritis.
