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
Medical gases, particularly oxygen and nitric oxide (NO), have attracted significant interest in clinical applications, notably wound healing, due to their role in enhancing cell proliferation, angiogenesis, and collagen deposition. However, the use of these gases has been limited by challenges such as inefficient gas delivery and potential toxicity to normal tissues. In this study, we elucidate a feasible approach using a porphyrin-based metal-organic framework (MOF), a unique material that shows immense potential for dual-gas-assisted wound healing. The MOF nanorods, meticulously designed, contain catalytically active manganese clusters, enabling spontaneous water decomposition and subsequent oxygen generation upon water exposure. The MOF incorporates Fe-chelated porphyrins, which not only serve as ligands connecting the manganese clusters but also exhibit a strong affinity with NO gas for the successful delivery of NO. The loaded NO, tethered to the MOF, can be released in a water environment. We employed a wound-healing assay to evaluate the efficacy of the NO-loaded MOF. After adding the MOF to fibroblast cell culture for O
