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
Herein, a fluorescent probe, DSNBD-GSH, was developed from dichlorosalicylaldehyde to monitor glutathione (GSH) in a cellular pulmonary ventilation model. Both the normoxia and hypoxia conditions were evaluated. DSNBD-GSH responded to GSH in a dosage-dependent manner with a fluorescence signal at 478 nm under the excitation of 365 nm. The solution tests indicated that DSNBD-GSH had relatively high sensitivity for GSH, and the photophysical properties were stable in various conditions. Other advantages included rapid response, high selectivity, and low cytotoxicity. Most significantly, monitoring the GSH level in both hypoxia and recovery status allows for visualization of ventilation-related redox changes. This work highlights a referenceable case for improving the pulmonary ventilation approach during the perioperative period.
