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

backgroundThe immunosuppressive tumor microenvironment in hepatocellular carcinoma (HCC) limits the efficacy of current immunotherapies. The interplay between the emerging inhibitory receptor NKG2A and its activating counterpart NKG2C, both binding HLA-E, and its interaction with the PD-1-PD-L1 pathway in cancer remains unclear. This study aims to delineate the functional network formed by these pathways in shaping the immunosuppressive landscape of HCC.

methodsWe analyzed public databases and performed immunohistochemistry on HCC tissues to assess HLA-E expression and prognostic relevance. Tumor-infiltrating lymphocytes from patient samples were examined by flow cytometry to evaluate the functional impact of NKG2A, NKG2C, and PD-1 expression on T and NK cells. Single-cell RNA and T cell receptor (TCR) sequencing were employed to characterize immune subset heterogeneity. Functional assays and mouse models were used to evaluate the effects of NKG2A and PD-1 blockade.

resultsIn the absence of CD8

conclusionsOur findings identify the NKG2A-HLA-E axis as an important immunoregulatory pathway associated with immune suppression in HCC and provide a rationale for further evaluation of combined NKG2A and PD-1 blockade strategies.
