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: Brain alterations related to "cortical plasticity" in patients with noise-induced hearing loss (NIHL) have been reported in studies related to hearing deprivation. This study aimed to investigate static functional network connectivity (sFNC) and dynamic functional network connectivity (dFNC) "cortical plasticity" features in patients with NIHL using independent component analysis (ICA). Methods: A total of 69 NIHL patients and 57 age- and education-matched healthy controls (HCs) were enrolled in this study. All participants were tested using the Mini-Mental State Examination (MMSE), Hamilton Anxiety Rating Scale (HAMA), and Tinnitus Handicap Inventory (THI), and scanned by three-dimensional T1-weighted imaging fast spoiled gradient echo (3D-T1WIFSPGR), resting-state functional magnetic resonance imaging (RS-fMRI) sequence. Resting-state networks (RSNs) were established based on ICA, and sFNC and dFNC analyses were performed. Associations between sFNC/dFNC abnormalities and clinical features related to NIHL were analyzed. Results: A total of 11 RSNs and 23 independent components (ICs) were identified, including auditory network (AUN), dorsal attention network (DAN), ventral attention network (VAN), default mode network (DMN), executive control network (ECN), higher visual network (HVIN), primary visual network (PVIN), left precuneus network, right precuneus network, salience network (SAN), and sensorimotor network (SMN). Compared with HCs, NIHL patients had increased sFNC between VAN (IC19) and ECN (IC29) [ Conclusions: Our findings support the view that hearing impairment due to exposure to excessive environmental noise can lead to changes in a variety of brain functions and provide new evidence that abnormalities in both sFNC and dFNC consist of shared and unique features in NIHL. sFNC combined with dFNC can provide a comprehensive view of brain activity, which contributes to a further understanding of the mechanism of abnormal brain functional activities in NIHL.
