1 · What the graph read from it

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.

2 · The registry

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

backgroundIcariside II (ICAII) is a flavonoid isolated from herb Epimedium that has been shown to improve erectile function in rats. However, ICAII's underlying mechanism remains unclear.

methodsType 2 diabetes mellitus erectile dysfunction (T2DMED) rats were induced by single intraperitoneal injection of 25 mg/kg streptozotocin (STZ) and fed a high-fat, high-sugar, and high-calorie diet for 8 weeks. In the control and T2DMED groups, rats were administered with normal saline; in the metformin (MET) group, rats were administered with MET at 0.2 g/kg/day; and in the ICAII + MET group, rats were administered with ICA II at 10 mg/kg/day and MET for 0.2 g/kg/day. The deposition of advanced glycation end products (AGEs), expression of receptor for AGEs (RAGEs), reactive oxygen species (ROS), and superoxide dismutase (SOD) activity, and corpus cavernosum smooth muscle cells (CCSMCs) mitochondrial autophagy were measured. We also evaluated the expression of LC3-II/I, Beclin-1, P70S6K, PI3K, AKT, mTOR, phospho-AKT, phospho-mTOR, and phospho-P70S6K.

resultsICAII and MET can improve erectile function, and decrease the levels of fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), and AGEs in rats with T2DMED. Furthermore, ICAII and MET can decrease excessive CCSMC mitochondrial autophagy and the level of RAGE and oxidant stress in rats with T2DMED. ICAII and MET may enhance signaling via the PI3K-AKT-mTOR pathway in order to reduce the excessive mitochondrial autophagy of CCSMCs.

conclusionsICAII may effectively improve penile erectile function via decreasing excessive CCSMCs mitochondrial autophagy, RAGE, and oxidant stress. Furthermore, ICAII may enhance signaling via the PI3K-AKT-mTOR pathway in order to reduce excessive CCSMC mitochondrial autophagy.
