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
purposeTwist1 is a transcription factor that regulates embryonic development, stemness, and differentiation, and can also stimulate initiation of tumorigenesis in peripheral solid cancers. However, its role in central nervous system tumors, including medulloblastoma (MB), the main type of malignant brain cancer that afflicts children, remains poorly understood. Here, we examined expression of Twist1, and its potential significance in prognosis, in different histological variants and molecular subgroups of MB.
methodsGene expression data for TWIST1 and corresponding overall survival (OS) of patients was analyzed in 612 MB samples using a previously described dataset. A cross-sectional analysis of Twist1 protein content in 24 MB tumor samples from patients was carried out by immunohistochemistry.
resultsTWIST1 transcript levels were higher in classic MB compared to desmoplastic tumors. Within samples with classic histology, higher TWIST1 expression was associated with a longer OS. Tumors in the SHH subgroup had lower TWIST1 expression compared to all other subgroups, and Group 4 showed lower expression than WNT tumors. In Group 4 MB, higher TWIST1 levels were associated with shorter OS, whereas patients with SHH tumors and higher TWIST1 levels showed longer OS. Twist1 protein was detectable in part of classic and LCA MB tumors belonging to the SHH, WNT, or Group 3/4 subgroups.
conclusionWe found opposite patterns of association between TWST1 and patient survival in Group 4 and SHH MB subgroups. Our results highlight the importance of stratifying tumors by molecular subgroup and histological classification when exploring novel potential biomarkers and therapeutic targets in MB.
