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

Bevacizumab (BEV) is known to improve progression-free survival (PFS) but not overall survival (OS) for newly diagnosed glioblastoma (ndGBM). Here, we evaluated the survival outcomes between temozolomide (TMZ)-only and TMZ + BEV treatments stratified based on the cyclooxygenase-2 (COX-2) expression, a rate-limiting enzyme involved in the cancer development. Fifty IDH-wildtype ndGBM patients treated between 2012 and 2023 were enrolled in this study. Pretreatment levels of COX-2 protein and mRNA expression were quantified, and survival analyses were performed based on the immunoreactivity score (IRS). Patients with high COX-2 expression (IRS ≥ 3, determined by its median) also exhibited higher COX-2 mRNA levels (∆Ct 6.43 ± 1.64 vs. 7.67 ± 0.81; p = 0.020). In patients with high COX-2 expression, TMZ + BEV had significantly longer median PFS and OS than those receiving TMZ-only (PFS: 22 vs. 8 months, p < 0.001; OS: 25 vs. 18 months, p = 0.009). In contrast, these benefits were not found in patients with low COX-2 expression (PFS: 12 vs. 15 months, p = 0.875; OS: 24 vs. 26 months, p = 0.775). Altogether, this study suggests that patients with high, but not low, COX-2 expression demonstrate survival benefits from the addition of BEV in ndGBM.
