1 · What the graph read from it

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.

2 · The registry

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

Matching of HLA-A, -B and -DRB1 is the gold standard in histocompatibility testing for kidney transplantation. A good HLA match reduces the risk of alloimmunisation, thereby decreasing the likelihood of graft failure and potentially enabling reduced immunosuppression therapy. However, the role of the non-classical HLA and MIC genes is not well established. We hypothesised that polymorphisms in these genes contribute additional risk of acute rejection after kidney transplantation, beyond what is explained by classical HLA mismatching. We developed and validated an oligogenic risk score based on ten polymorphisms in the HLA-E, -F, -G, MICA and MICB genes associated with time to acute rejection using Cox proportional hazards analysis in a single centre retrospective cohort of 1025 Finnish adult kidney transplant recipient-donor pairs. The score, particularly at the extreme ends, that is, the 1st and 10th deciles, was associated with rejection-free survival in both the discovery cohort (Cox multivariable model HR 1.20, 95% CI 1.08-1.33, p-value 4.350 × 10
