IgG In Saliva, GCF, and Serum in Young Patients With Grade C Molar Incisor Pattern Periodontitis.
Article in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis cross-sectional study aimed to investigate immunoglobulin G levels in saliva, gingival crevicular fluid, and serum samples from young patients with grade C molar incisor pattern periodontitis (C/MIP) and age-matched periodontitis-free controls.
methodsSaliva, gingival crevicular fluid, and blood samples were collected from 62 patients, divided into 31 cases and 31 periodontitis-free age-matched controls. Saliva and blood samples were centrifuged to extract supernatant and serum. Gingival crevicular fluid periopapers were eluted. Human total immunoglobulin G levels were assessed using an Enzyme-Linked Immunosorbent Assay.
resultsAfter adjusting for covariates, cases had higher Immunoglobulin G levels in saliva (p = 0.005), gingival crevicular fluid (p < 0.001) than controls; however, serum did not reach the significant threshold (p = 0.137). Among other factors contributing to immunoglobulin G levels, males had higher serum immunoglobulin G than females (p = 0.018), and serum immunoglobulin G levels increased with age (p = 0.033). Gender and ethnicity subgroup analyses revealed that C/MIP males had higher saliva IgG (p = 0.018) than control males, and both genders had higher GCF IgG than controls (p ≤ 0.001). C/MIP Caucasians had elevated saliva (p = 0.011) and GCF IgG p = (0.003) compared to the controls, and Asians had higher GCF IgG than the controls (p = 0.011).
conclusionThis study shows for the first time that C/MIP cases have higher Immunoglobulin G levels than controls in saliva and gingival crevicular fluid, confirming its association with C/MIP pathogenesis and suggesting that it could be a potential biomarker in grade C molar incisor pattern periodontitis. Further research on a larger sample size is needed.
