Association of vitamin D and platelet-to-lymphocyte ratio in treatment escalation risk for newly diagnosed Crohn's disease adults.
Article in Nutrition journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAccumulating research has implicated that vitamin D (VD) may be important in the pathogenesis of Crohn's disease (CD), while the platelet-to-lymphocyte ratio (PLR) is emerging as a biomarker in immune disorders. However, the synergistic effect of VD and PLR on treatment escalation in newly diagnosed CD patients remains unclear. Therefore, this study aims to assess the interaction between PLR and VD on the subsequent use of infliximab and/or immunosuppressants in patients with CD.
methodsNewly diagnosed CD patients were selected from the Sir Run Run Shaw Hospital Inflammatory Bowel Disease Biobank (SRRSH-IBC). COX proportional hazards models were employed to assess the association between VD, PLR, and treatment escalation among CD patients.
resultsAmong 108 newly diagnosed CD adult patients, vitamin D deficiency (VDD) was prevalent (78.7%). Compared to CD patients without VDD, those with VDD exhibited a higher risk of treatment escalation, i.e., using infliximab and/or immunosuppressants (HR = 3.22, 95% CI = 1.24-8.35, P = 0.016). There is a clear trend of decreasing risk of treatment escalation as VD levels elevating (HR = 0.26, 95% CI = 0.09-0.76, P for trend = 0.014). The stratified analysis revealed a noteworthy interaction between PLR and VD levels concerning treatment escalation. Baseline VDD amplified the risk of treatment escalation among patients with elevated PLR (HR = 4.17, 95% CI = 1.51-11.53, P
conclusionThis study underscores a significant interplay between VD levels and PLR in influencing treatment outcomes in CD. VDD exacerbates the risk of treatment escalation primarily in individuals with heightened PLR levels, highlighting the combined impact of vitamin D status and inflammation on disease progression of CD.
