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.

Abstract

introductionCraniospinal irradiation (CSI) forms an integral role in the management of primary brain tumors like embryonal tumors (medulloblastoma), non-seminomatous germ cell tumors, metastatic ependymoma, etc. The cranial component with radiation of whole brain and boost can lead to decline in neurocognitive function. Memantine is an NMDA receptor antagonist with an established role in reducing radiation-induced neurocognitive decline in patients treated with whole brain radiotherapy, but the benefit in pediatric and adults treated with CSI remains unclear.

methodsThis is a phase 3 open-label, randomized controlled trial. Pediatric and young adults (5 to 39 years) treated with CSI will be eligible for the study. Patients will be randomized in 1: 1 accounting for stratification factors such as age, CSI dose, location of tumor boost, and use of chemotherapy. Patients in the experimental arm will receive memantine 5 mg once daily for 1 week, 5 mg twice daily for 1 week, and finally escalated to 10 mg twice daily for 6 months. The primary endpoint will be cognitive deterioration-free survival (CDFS) at 2 years, with secondary endpoints being safety and compliance of memantine, slope of decline of neurocognitive scores, and survival. To demonstrate the improvement of 2-year CDFS of 75% in memantine arm compared to 50% in standard arm, 84 patients need to be evaluated (alpha 0.05 and power 80%). Considering an attrition of 20%, a total of 101 patients will be randomized. DISCUSSION: If trial results are positive memantine will be established as a new standard of care to be used with CSI.

trial registrationThe trial is registered on ClinicalTrials.gov (study identifier NCT06275035) and Clinical Trial Registry India (CTRI/2024/02/062273).
