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

A glioblastoma (GBM) patient with a high tumor mutation burden (TMB-high) and mismatch repair deficiency (dMMR) exhibited a significant response to pembrolizumab, an immune checkpoint inhibitor (ICI), despite prior treatment with temozolomide (TMZ), known to induce hypermutation and potential resistance to ICIs. The rapid disease progression, indicated by 80% Ki67 positivity, was markedly countered by the positive outcome of pembrolizumab treatment. This case challenges traditional GBM treatment paradigms, demonstrating the potential of precision oncology in patients with significant TMB and dMMR, and underscores the importance of comprehensive genomic profiling in guiding clinical decisions in GBM management.
