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
Purpose: Neuron-specific enolase (NSE) is a type of glycolytic enzyme enolase. As NSE is predominantly localized in endocrine cells and neurons, it is frequently recognized as a specific biomarker for peripheral neuroendocrine cells and neurons. Recently, numerous clinical studies have investigated the correlation between peripheral blood NSE levels and depression; however, the findings remain inconsistent. The objective of this study is to systematically evaluate peripheral blood NSE levels in patients with various types of depression. Methods: We conducted an extensive literature review using various databases such as PubMed, Embase, Cochrane Library, Web of Science, Wanfang, and China National Knowledge Infrastructure (CNKI). A random-effects model was utilized to compute the pooled effect size (ES) (Hedges' Results: A total of 1175 records were screened for initial eligibility, and 18 reports reported in 18 studies that met the inclusion criteria were included in the meta-analysis. The primary analysis revealed that abnormally elevated levels of NSE in peripheral blood are closely related to the risk of occurrence of major depressive disorder (MDD) or poststroke depression (PSD). Analysis results from different groups on MDD or PSD showed similar outcomes. Sensitivity analysis confirmed the robustness of our findings. The findings on publication bias suggested that this study did not exhibit any significant publication bias. Conclusions: The findings of our study suggest that abnormally elevated NSE levels in peripheral blood are closely related to the risk of depression, especially MDD and PSD. These findings offer valuable references for the monitoring and early warning of depression. However, the applicability to other subtypes of depression and the clinical translational value requires further validation. In the future, clinical studies with more participants are necessary.
