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

purposeTo explore the systemic inflammatory biomarker changes throughout the entire treatment period from the perspective of the extent of surgical resection and their possible role in predicting survival in glioblastoma.

methodsA retrospective analysis was performed on 41 glioblastoma patients who underwent either gross total resection (GTR, n = 14) or subtotal resection (STR, n = 27), followed by adjuvant radiotherapy (60 Gy) with concurrent and adjuvant temozolomide. Inflammatory biomarkers, including neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), monocyte-lymphocyte ratio (MLR), systemic inflammatory index (SII), and systemic inflammation response index (SIRI), were calculated from routine blood tests. These biomarkers were measured at specific times: preoperatively, before radiotherapy, after chemoradiotherapy, at the sixth cycle of temozolomide, and at radiological and/or clinical progression. Survival outcomes were analyzed using the Kaplan-Meier method.

resultsMedian follow-up was 21 months. Patients with GTR had significantly better 2-year progression-free survival (42.9% vs. 18.5%, p = 0.033) and overall survival (50% vs. 33.3%, p = 0.045) compared to those with STR. Inflammatory biomarker levels remained higher in the STR group both after RT and following the sixth cycle of temozolomide than in the GTR group. Changes in biomarker levels were not affected by the interval between surgery and radiotherapy, Ki-67 status, the number of chemotherapy cycles, age, or gender.

conclusionLong-term patterns of systemic inflammatory biomarkers may reflect a higher inflammatory burden and a poorer prognosis in patients with glioblastoma. The predictive role of these biomarkers should be evaluated in prospectively collected, molecularly characterized cohorts.
