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
Nasal sprays were introduced several years ago to support the treatment of allergic rhinitis. These sprays may come in direct contact with directly exposed nasoseptal cartilage (e.g. is case of nasoseptal perforation). To date, no studies investigated the effects of nasal sprays on cartilage tissues and cells. Therefore, our aim was to analyze the influence of two different nasal spray types (thixotropic and liposomal) on the vitality of nasoseptal chondrocytes. Human chondrocytes were isolated from surgically dissected tissues. Alternatively, nasal septa (porcine and human) tissue explants were used. The cell or explant cultures were treated with nasal sprays for 4-24 h. As a read-out, cell vitality and gene and protein expression profiles of type I and II collagen, SOX 9 and matrix metalloproteinase MMP-1 were compared to the untreated controls by means of real-time RT-PCR and immunostaining. Using the liposomal, but not thixotropic nasal spray in an explant or chondrocyte in vitro culture led to increased cell death, as compared to the untreated controls. A trend towards suppression of type II collagen and SOX 9 on protein level was found in cultures exposed to liposomal nasal spray, as compared to the controls. The thixotropic nasal spray has not affected the nasoseptal chondrocytes. Further studies with the use of viable nasoseptal cartilage explants and particularly using an in vivo animal model of exposed nasoseptal cartilage are necessary to clear the effect of liposomal spray on chondrocytes.
