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
The study aims to elucidate the therapeutic mechanism of Baicalin (BAI) in alleviating cartilage injury in osteoarthritic (OA) rat models, concentrating on its regulation of the miR-766-3p/AIFM1 axis. An OA rat model was developed with unilateral anterior cruciate ligament transection (ACLT). Interventions comprised of BAI treatment and intra-articular administration of miR-766-3p inhibitor. For evaluation, histopathological staining was conducted to investigate the pathological severity of knee cartilage injury. The levels of oxidative stress (OS) indicators including MDA, SOD, and GSH-Px, were quantified using colorimetric assays. Inflammatory factors (IFs; TNF-?, IL-1?, and IL-6) in knee joint lavage fluids were assessed using ELISA, while RT-PCR was employed to quantify miR-766-3p expression. TUNEL apoptosis staining was utilized to detect chondrocyte apoptosis, and western blotting examined autophagy-related markers (LC3, Beclin, p62), extracellular matrix (ECM) synthesis-associated indices (COL2A, ACAN, MMP13), and apoptosis-inducing factor mitochondrion-associated 1 (AIFM1). Histological examination revealed a marked amelioration of cartilage injury in the BAI-treated OA rat models compared to controls. BAI treatment significantly reduced inflammation and OS of knee joint fluid, activated autophagy, and decreased chondrocyte apoptosis and ECM degradation. Interestingly, the inhibitory effects of BAI on these pathological markers were significantly decreased by the miR-766-3p inhibitor. Further assessment revealed that BAI efficiently promoted miR-766-3p expression while inhibiting AIFM1 protein expression. BAI potentially mitigates articular cartilage injury in OA rats, likely through modulation of miR-766-3p/AIFM1 axis. Keywords: Baicalin, microRNA, AIFM1, Osteoarthritisv, Rat.
