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
Significance: Miniature multiphoton microscopy has revolutionized neuronal imaging in freely behaving animals. However, its shallow depth of field-a result of high axial resolution-combined with a limited field of view (FOV), makes it challenging for researchers to identify regions of interest in three-dimensional space across multimillimeter cranial windows, thereby reducing the system's ease of use. Aim: We aimed to develop a multimodal imaging platform with enhanced guidance and a standardized workflow tailored for efficient imaging of freely behaving animals. Approach: We present a wide-field fluorescence navigation system (WF-Nav) featuring a 90-mm working distance, a 4-mm FOV, and single-cell resolution, enabling rapid and precise localization of designated regions. By seamlessly integrating this navigation system with our prior miniature multiphoton microscopes, we established a multimodal platform that supports versatile imaging modalities and seamless transitions to two- or three-photon imaging. Building on this integration, we developed a streamlined workflow for efficient, user-friendly imaging in freely behaving mice. Results: We validated the system through large-FOV imaging (4 mm), dual-color imaging (920 and 1030 nm), and deep-brain neuronal imaging (up to 1 mm) in either awake mice or freely moving mice. The entire experimental procedure was completed in Conclusions: We have developed a comprehensive imaging platform that integrates a single-photon wide-field navigation system with miniature two-photon and three-photon microscopy, leveraging the strengths of each modality. Building on this platform, we established a streamlined workflow tailored for imaging freely behaving animals, markedly expanding its applicability and improving efficiency.
