The Presence of Non-HLA Antibody With DSA Is Associated With Moderate to Severe T Cell-Mediated Rejection in Liver Transplant Recipients.
Article in Clinical transplantation, 2026. 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
backgroundAntibodies to donor HLA (DSA) and non-HLA antigens are associated with detrimental outcomes in kidney, heart, and lung transplants. Such data are scarce in liver transplants (LTx). We aim to study the roles of DSA and non-HLA antibodies in T-cell-mediated rejection (TCMR) of LTx.
methodsAllograft biopsies (n = 103) from adult LTx recipients were studied. Biopsy-paired serums were retrospectively tested for anti-angiotensin II type 1 receptor (AT1R) and the Luminex panel of 60 non-HLA Antibodies.
resultsTCMR was detected in 59 of 103 (57.3%) biopsies. Twenty-six biopsies were categorized as moderate-severe (MS-TCMR), 77 as negative-mild (NM-TCMR). DSA was positive in 95/103 (92.2%) cases and wasn't associated with MS-TCMR. Anti-AT1R antibodies were elevated in serum paired with MS-TCMR vs. NM-TCMR (18.8[15.2-40.0] vs. 13.0[10.0-21.5] U/ml, p < 0.01). Positive anti-AT1R antibodies were associated with a higher incidence of MS-TCMR (HR = 12.4[1.5-101.6], p = 0.02). A panel of 18 non-HLA Abs was significantly associated with MS-TCMR. The number of panel-18 non-HLA antibodies was higher with MS-TCMR vs. NM-TCMR (3[2-5] vs. 1[0-1], p < 0.001). The incidence of MS-TCMR was higher in cases with panel-18 non-HLA antibodies ≥3 vs. <3 (HR = 19.6[6.0-64.8], p < 0.001). The frequency of MS-TCMR was the highest when DSA, anti-AT1R, and panel-18 non-HLA antibodies were all present.
conclusionsNon-HLA antibodies to AT1R or the Luminex panel are associated with MS-TCMR in LTx biopsies. The incidence of MS-TCMR is higher when non-HLA antibodies are present concomitantly with DSA, indicating an additive effect. Further studies are warranted to investigate the utility of routinely monitoring DSA and non-HLA antibodies in LTx recipients.
