Revealing the effects of various immune cells in anorexia nervosa: Evidence from Mendelian randomization.
Article in Medicine, 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
The aim of this study was to assess the causal relationship between immune cells and anorexia nervosa (AN) by Mendelian randomization (MR). Data on immune cell phenotypes and AN were obtained from genome-wide association studies. Next, single nucleotide polymorphisms included in the MR analysis were screened according the basic assumptions. Furthermore, inverse variance weighted was used as the main method for MR analysis to evaluate the causal effect of immune cell phenotypes on AN. Finally, MR-Egger intercept, Cochran Q, and leave-one-out sensitivity analyses were used to assess horizontal pleiotropy, heterogeneity, and robustness, respectively. The MR analysis showed that NKT %lymphocyte (OR 1.201, 95% CI = 1.021-1.411, P = .027), NKT %T cell (OR 1.258, 95%CI 1.043-1.519, P = .017), double negative (DN) (CD4-CD8-) NKT %lymphocyte (OR 1.235, 95%CI 1.074-1.420, P = .003), DN (CD4-CD8-) NKT %T cell (OR 1.222, 95%CI 1.060-1.410, P = .006), CD8dim NKT absolute count (OR 1.225, 95%CI 1.045-1.436, P = .012), CD8dim NKT %lymphocyte (OR 1.214, 95%CI 1.043-1.414, P = .012), CD8dim NKT %T cell (OR 1.215, 95%CI 1.035-1.425, P = .017), CD16-CD56 on NKT (OR 1.193, 95%CI 1.014-1.402, P = .033), CD28 + CD45RA + CD8br %T cell (OR 1.020, 95%CI 1.002-1.037, P = .025) were associated with increased genetic susceptibility to AN. MR-Egger showed no horizontal pleiotropy (P ≥ .05). Cochran Q and sensitivity analysis showed that the results were not heterogeneous and were robust. This MR analysis revealed 9 immune cell phenotypes related to increased genetic susceptibility to AN, emphasizing the importance of NKT and CD8 in AN. This finding provides new insights for understanding the pathogenesis of AN and developing immune-targeted drugs.
