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
CCN proteins are matricellular proteins and are important modulators of development and function of adult organs. However, there is no literature reporting the localization of CCN proteins during postnatal tooth development and the formation of periodontium. Therefore, the aim of our study was to investigate the expression of CCN1, CCN3, CCN4, CCN5 and CCN6 in the developing postnatal teeth. Wistar rats were used at postnatal (PN) 3.5, 7, 16 and 21 days and maxillas were processed for immunohistochemistry. At PN3.5 and PN7, preameloblasts (PA), secretory ameloblasts (SA), odontoblasts (OD) and dental pulp (DP) showed moderate to strong staining for CCN1, CCN4 and CCN6 respectively. CCN5 was intensely expressed in predentin, whereas CCN5 was undetectable in PA, SA, OD and DP. At PN16 and PN21, moderate to strong reaction with CCN1, CCN4 and CCN6 was evident in OD, DP, reduced enamel epithelium (REE), osteoblasts (OB) and periodontal ligament (PDL) respectively, while CCN5 was negative to weakly expressed in REE, OD, DP, OB, PDL and osteocytes (OC). Interestingly, the expression of CCN1, CCN4 and CCN6 was initially negative at PN16 but strong at PN21 in OC. Furthermore, there was no staining for CCN3 in the tissues studied. These results demonstrated that the expression pattern of CCN1, CCN4 and CCN6 is similar and inversely correlated with that of CCN3. CCN5 exhibits a unique distribution pattern. These data indicate that CCN proteins might play regulatory roles in amelogenesis, dentinogenesis, osteogenesis and PDL homeostasis.
