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
backgroundA wide range of non-neoplastic brain lesions can mimic tumors on magnetic resonance imaging (MRI), creating diagnostic challenges. Although MRI is the gold standard for evaluating brain lesions, differentiating between neoplastic and non-neoplastic lesions, as well as high- and low-grade tumors, can be difficult, sometimes leading to unnecessary biopsies. Magnetic resonance spectroscopy (MRS) helps by analyzing biochemical and metabolic processes, especially when conventional MRI falls short. Perfusion MRI (MRP), sensitive to microvasculature, is used to classify tumors, detect strokes, and evaluate other conditions. Both methods are non-invasive alternatives to radiation-based imaging techniques.
methodsA retrospective, cross-sectional study of patients with intracranial lesions who underwent MRS and perfusion imaging in a tertiary hospital in the Philippines were analyzed.
resultsThe study included 37 patients (28 male, 9 female) aged 19-78, with MRS and MRP data collected. Seizures were the most common symptom (24%), followed by weakness, headache, dizziness, and visual changes. Notably, 24% were asymptomatic. Among all patients examined by MRI with MRS and MRP for intracranial mass lesions, 60% were neoplasm, 21.6% were radiation necrosis, 5.4% were demyelinating lesions, 2.7% were infection, and 2.7% were vascular lesions. Biopsies were performed on nine patients, with seven correlating to MR results. Thirty-five point one percent of patients showed no clinical change, while 18.9% fully recovered. Imaging revealed lesion reduction in 35.1% of patients, no change in 29.7%, and lesion growth in 18.9%.
conclusionMRS and MRP complement conventional MRI in distinguishing neoplastic from non-neoplastic lesions, differentiation of types of malignancies, and differentiating tumor recurrence from radiation necrosis, offering a non-invasive way of catechizing the biochemical make-up of intracranial lesions.
