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: Based on the secreted frizzled-related protein 2 (SFRP2)-Wnt/β-catenin signaling pathway, this study explored the effect and mechanism of Cuiru Keli (CRKL) in the treatment of postpartum hypogalactia. Methods: A rat model of postpartum hypogalactia was established by gavaging 2 mL of 1.6 mg/mL bromocriptine mesylate to female rats on the third day after delivery. Female rats with a delivery time difference of less than 48 hours were selected and randomly assigned to 7 groups, including a normal group (without any modeling or medication), a model group, a CRKL low-dose group of model group model rats receiving CRKL at the dose of 3 g/kg, a CRKL medium-dose group of model rats receiving CRKL at the dose of 6 g/kg, a CRKL high-dose group of model rats receiving CRKL at the dose of 9 g/kg, a positive drug group of model rats receiving domperidone at the dose of 3 mg/kg, and a negative control (NC) group of model rats receiving normal saline. Each group contained 6 rats. Except for the normal and model groups, the remaining 5 groups were continuously administered with the respective intervention drugs at the specified doses by gavage once a day for 10 days. Changes in the total litter mass of the offspring in the 7 groups within 10 days were measured, and HE staining was performed to identify pathological changes in the mammary tissue (MT). Six groups of rats (excluding the positive control group) were used to observe the pathological changes of eosinophils in pituitary tissue. ELISA was performed to determine the content of prolactin (PRL) in serum, immunohistochemical staining was used to determine the expression of prolactin receptor (PRLR) in MT, and RT-qPCR was used to determine the mRNA expression of genes related to lactation in MT. Network pharmacology and molecular docking were used to study the therapeutic effect and mechanism of CRKL on postpartum hypogalactia, particularly whether it acted through the SFRP2-Wnt/β-catenin signaling pathway. The mechanism of CRKL treatment was further validated by detecting mRNA (RT-qPCR) and protein expression (Western blot) of related pathway genes. Cell experiments were conducted using primary culture rat mammary epithelial cells (RMEC) from rat MT. RMEC were divided into four groups, including a normal group (primary culture RMEC, untreated), Results: In this study, CRKL was administered at a dose of 3 g/kg in the CRKL low-dose group, 6 g/kg in the medium-dose group, and 9 g/kg in the high-dose group ( Conclusion: CRKL alleviates postpartum hypogalactia through the SFRP2-Wnt/β-catenin signaling pathway. SFRP2 might be a potential new target for the diagnosis and treatment of postpartum hypogalactia. This reveals a new mechanism of CRKL in treating postpartum hypogalactia and promotes its clinical application.
