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
The need for direct biomaterial-based delivery of growth factors to wound surfaces to aid in wound healing emphasizes the importance of interfacial interactions between the biomaterial and the wound surface. These interactions include the spatial localization of growth factor, the surface intensity of growth factor in contact with the wound, and the release profile of growth factor to the wound surface. The authors report the use of time-of-flight secondary ion mass spectrometry to determine the relationship between biomaterial surface chemistry and the spatial localization of growth factor. They have implemented a novel application of total internal reflectance fluorescence (TIRF) microscopy to measure the surface intensity and release of growth factor in contact with a glass substrate that has been used to model a wound surface. Detailed information regarding TIRF experiments has been included to aid in future studies regarding the biomaterial delivery to interfaces. The authors have evaluated the effects of (hydroxyethyl)methacrylate (HEMA) homopolymer, 5.89% methyl methacrylate/HEMA, and 5.89% methacrylic acid/HEMA surface chemistry on the spatial localization of AlexaFluor 488-labeled keratinocyte growth factor (AF488-KGF), AF488-KGF surface intensity at the copolymer surface, and release to a glass substrate. KGF is known to promote re-epithelialization in wound healing. The results show that the two copolymers allow for increased surface coverage, surface intensity, and release of AF488-KGF in comparison to the homopolymer. It is likely that differences in these three aspects could have a profound effect on the wound healing response.
