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
Background: Chronic stress can not only lead to depression-like behavior but also sexual dysfunction. Morinda officinalis oligosaccharides (MOO) is a formula of traditional Chinese medicine commonly used in invigorating the kidney and strengthening Yang, and relieving depression. Aim: This study was designed to explore the effects and mechanisms of MOO in treating chronic stress-induced depression as well as sexual dysfunction. Methods: The sucrose preference test, forced swimming test (FST) and novelty-suppressed feeding test (NSFT) were carried out to evaluate the depression status. Sexual behavior was tested on all mice, then the extent of damage to the testicles and epididymis was assessed by H&E staining; Serum sex hormone and neurotransmitters were assessed in the plasma by Enzyme-Linked Immunosorbent Assay. The testicular tissues were applied with the kit for the detection of antioxidant-related indexes and reproductive-related hormones. Outcomes: The study evaluates the effects of MOO on depression-like behaviors and sexual function levels in CUMS-induced mice by analyzing the behavioral tests, histopathological staining of testis and epididymis, sex hormones, antioxidant capacity, neurotransmitter levels, and sexual behavior abilities of mice in each group. Results: CUMS led to mice depression and plasma neurotransmitter levels decreased. Accompanying sexual dysfunction in depressed mice was also manifested in many aspects. Compared with the control group, the capture latency and mount latency of male mice in model group were significantly prolonged. HE showed that testicular and epididymal tissues of mice in the CUMS group were severely vacuolated. Testicular marker enzymes, antioxidant indexes and sex hormones were disorganized. The sperm concentration and viability in the epididymis of the mice in model group were significantly reduced. It was suggested that MOO could improve the damage caused by CUMS, and improve the sperm quality of the model mice. Clinical Translation: MOO are promising to be translated into a potential therapeutic drug for clinically improving chronic stress-related depression and sexual dysfunction. Strengths and Limitations: Multi-dimensional verification confirms that MOO can effectively alleviate depressive states and sexual dysfunction in CUMS-induced mice. Future studies should explore the in-depth mechanisms underlying its antidepressant and anti-sexual dysfunction effects based on relevant signaling pathways. Conclusion: These results suggest that MOO can regulate sexual dysfunction and play a protective role in neurodevelopment during CUMS by regulating sex hormones.
