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 2 most prevalent types of spinal ependymal tumors are myxopapillary ependymomas (MPE) and spinal ependymomas (SP-EPN). Based on molecular data from bulk tumor samples, we previously identified clinically relevant subtypes with poor (MPE-A; SP-EPN-A) and favorable progression-free survival (MPE-B; SP-EPN-B). However, detailed cellular composition, molecular heterogeneity, and features of tumor progression are largely unknown.

methodsWe performed singlenucleus transcriptomic sequencing of 25 formalin-fixed and paraffin-embedded spinal ependymal tumors, including all MPE and SP-EPN subtypes and 6 paired primary and relapsed MPE-A.

resultsEpendymoma subtypes presented with a broad, but comparable tumor microenvironment. Furthermore, neoplastic cells demonstrated inter- and intratumoral heterogeneity regarding cancer cell state composition. Overall, MPE tumors exhibited a significantly higher abundance of the astrocytic state, whereas a ciliated state was more prevalent in SP-EPN. Also, transcriptome-inferred copy number variation (CNV) profiles revealed tumor cell clusters with distinct chromosomal alterations across tumors, suggesting subclonal neoplastic growth. Compared to normal human spinal cord cell populations, MPE tumor cells displayed similarities to astrocytes and ependymal cells, whereas SP-EPN exclusively matched ependymal cells. Myxopapillary ependymomas of type A demonstrated a distinct profile, being similar to the roof and floor plate of the developing spinal cord. Paired primary and relapsed MPE-A revealed mostly similar histology, epigenetics, CNV profiles, and cellular composition of neoplastic cells.

conclusionSingle-nucleus transcriptomic sequencing provides valuable insights into the molecular composition of spinal ependymoma types and subtypes and may pave the way for a better understanding of tumor evolution and identification of therapeutic targets.
