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

backgroundThe concept of maximally safe resection (MSR) has been shown to improve clinical outcomes in the treatment of high-grade gliomas (HGGs). To achieve MSR, surgical adjuncts such as functional imaging, neuronavigation, intraoperative mapping, ultrasound, and fluorescence-guided surgery are routinely used. 5-Aminolevulinic acid (5-ALA) is an oral agent that has been increasingly adopted in fluorescence-guided resection of HGG. In randomized clinical trials of 5-ALA, it has been shown to increase the extent of resection and progression-free survival in HGG. Current commercially available 5-ALA detection systems are all microscope-based and can sometimes be cumbersome to use.

objectiveTo present our experience using a novel 5-ALA-enabled surgical loupe system.

methods5-ALA-enabled loupes were used in 11 consecutive patients with either suspected HGG on magnetic resonance imaging or recurrence of known lesions. Lesion appearance was examined under white light, 5-ALA loupes, and a 5-ALA microscope. Tumor specimens were checked for fluorescence and sent for pathologic examination.

resultsIn our experience, a 5-ALA-enabled surgical loupe system offers excellent visualization of 5-ALA in patients with HGG. In 10 of 11 patients, fluorescent tissue was confirmed to be high-grade glioma by pathology. In 1 patient, tissue was not fluorescent, and final pathology was World Health Organization grade I meningioma.

conclusionA 5-ALA-enabled surgical loupe system offers excellent intraoperative visualization of 5-ALA fluorescence in HGG and can be a viable surgical adjunct for achieving MSR of HGG.
