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
objectivesThe aetiology and treatment of molar-incisor hypomineralisation (MIH) may be further investigated by understanding the proteomic changes associated with the defect. The present scoping review aimed to systematically examine existing literature on salivary and enamel proteomics related to MIH, characterising specific proteins associated with the defect and evaluating methodologies employed in current proteomic studies.
methodsThe review was conducted following the PRISMA-ScR guidelines. A systematic search of PUBMED, SCOPUS, EMBASE, Web of Science, and Cochrane databases was performed for clinical trials and observational studies published until February 2025. Inclusion criteria encompassed studies on human samples examining proteomics related to MIH with a control group. Two reviewers independently screened articles for eligibility.
resultsSix studies met the inclusion criteria. Key findings revealed significant alterations in protein composition in MIH-affected enamel and saliva, including proteins, such as chitinase 1, human serum albumin, collagen alpha 1 (I), collagen alpha 2 (I), alpha-1-antitrypsin, and dentin sialophosphoprotein (DSPP). In particular, MIH samples exhibited overexpression of proteins linked to inflammation and stress responses, including albumin, fibrinogen, and complement C3. Proteomic analyses highlighted the potential of salivary and enamel proteins as biomarkers for MIH, although variations in research methodologies presented challenges in establishing standardised biomarkers.
conclusionsThis review underscores the importance of proteomic analysis in understanding the molecular mechanisms underlying MIH. Identifying specific proteins may enhance diagnostic and therapeutic strategies for affected children. However, substantial research gaps remain, particularly in the exploration of various proteomic sources and the dynamic nature of salivary proteins.
