Shared Inflammatory Mechanisms in Psoriasis and Periodontitis: A Cross-Sectional Study.
Article in Oral diseases, 2026. 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
backgroundPsoriasis and periodontitis are chronic inflammatory diseases fueled by immune dysregulation. This study investigated their association by evaluating periodontal parameters and tumor necrosis factor-alpha (TNF-α), interleukin-17A (IL-17A), and YKL-40 levels in gingival crevicular fluid (GCF) and serum.
methodsSixty individuals were assigned into three groups: healthy controls (C), periodontitis (P), and psoriasis with periodontitis (PS + P). Periodontal indices, including plaque index (PI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL), were recorded. TNF-α, IL-17A, and YKL-40 concentrations in GCF and serum were analyzed using enzyme-linked immunosorbent assay (ELISA).
resultsPeriodontal parameters were markedly higher in both periodontitis groups than in controls (p < 0.05). Serum TNF-α and IL-17A levels were highest in the PS + P group. GCF TNF-α was increased in both P and PS + P groups, while GCF IL-17A was elevated only in the P group. GCF and serum YKL-40 were elevated in both periodontitis groups, without a significant intergroup difference. GCF TNF-α correlated with PD (p < 0.001), CAL (p < 0.001) and PI (p < 0.001), while GCF YKL-40 correlated with CAL (p < 0.001) and BOP (p < 0.001). In the PS + P group, GCF YKL-40 also correlated with GCF TNF-α (p = 0.001) and IL-17A (p = 0.003).
conclusionThese findings suggest a possible influence of psoriasis on periodontal inflammatory responses.
