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
backgroundNasal irrigation is often used for managing sinonasal conditions and maintaining nasal hygiene, which is critical to overall nasal health and to provide protection against airborne contaminants and pathogens. However, studies comparing efficacies of different solutions are needed. PURPOSE: This in vitro study evaluated the ionic balance of an isotonic diluted seawater solution (Stérimar Nasal Hygiene, SNH) and its safety and efficacy for regular nasal hygiene in comparison to electrodialyzed seawater (EDS). MATERIALS AND
methodsIonic balance of SNH, EDS and pure seawater was measured by mass spectrometry and chromatography to be compared to the ionic balance of human plasma as reported in the literature. Safety was measured through cytotoxicity (lactate dehydrogenase release) and pro-inflammation (interleukin-8 secretion) assays using a 3D-reconstituted human nasal epithelium model. For efficacy, adenosine 5'-triphosphate (ATP) release assays, and histological (alcian blue) and immunohistochemical (aquaporin 3) stainings were performed on tissues under hypotonic challenge where saline solution was used as the negative control.
resultsCompared to EDS, the ionic balance of SNH was more similar to human plasma and pure seawater. SNH reduced hypotonic stress-associated ATP release and maintained tissue morphology more effectively and lastingly compared to EDS. Both solutions were safe to use on nasal epithelium, as neither of them caused cytotoxicity or induced (pro-) inflammation.
conclusionIn comparison to EDS, this study confirms the safety and efficacy of SNH in maintaining good nasal hygiene consistent with its benefits reported in clinical trials.
