Biopsy of diffuse midline glioma is safe and impacts targeted therapy: a systematic review and meta-analysis.

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.
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 quantify the safety and utility of biopsy of pediatric diffuse midline glioma (DMG).
methodsThis study was conducted in accordance with PRISMA guidelines. PubMed, Embase, Scopus, and Web of Science were queried for relevant articles from inception until June 2023. Two reviewers identified all articles that included diagnostic yield, morbidity, and mortality rates for pediatric DMG patients. Studies that did not present original data or were not in English or peer-reviewed were excluded. Meta-analysis was conducted in R using Freeman-Tukey or logit transformation and DerSimonian-Laird random-effects models. The risk of bias was assessed using the Newcastle-Ottawa Scale. A protocol for this review was not registered.
resultsWe identified 381 patients from ten studies that met all criteria. DMG biopsy is safe overall (0% mortality, 95% CI: 0-0.6%; 11.0% morbidity, 95% CI: 4.8-18.9%) and has a high diagnostic yield (99.9%, 95% CI: 98.5-100%). The use of stereotactic biopsy is a significant moderator of morbidity (p = 0.0238). Molecular targets can be identified in approximately 53.4% of tumors (95% CI: 37.0-69.0%), although targeted therapies are only delivered in about 33.5% of all cases (95% CI: 24.4-44.1%). Heterogeneity was high for morbidity and identification of targets. The risk of bias was low for all studies.
conclusionWe conducted the first meta-analysis of DMG biopsy to show that it is safe, effective, and able to identify relevant molecular targets that impact targeted therapy.
