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

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutations in either the TSC1 or TSC2 genes and characterized by developmental brain abnormalities. We defined the spectrum of brain abnormalities in fetal TSC brain ranging from 23 to 38 gestational weeks. We hypothesized (i) prenatal activation of the target-of-rapamycin complex 1 (TORC1) signaling pathway; and (ii) activation of inflammatory pathways in fetal brain lesions. Immunocytochemical analysis of cortical tubers, as well as subependymal lesions in all cases confirmed the cell-associated activation of the TORC1 signaling pathway in both the cortical tubers and subependymal lesions (including a congenital subependymal giant cell astrocytoma) with expression of pS6, p4EBP1 and c-myc proteins, as well as of p70 S6 kinase 1. The lesions contained macrophages and T-lymphocytes; giant cells within the lesions expressed inflammatory response markers including major histocompatibility complex class I and II, Toll-like receptors (TLR) 2 and 4 and receptor for advanced glycation end products (RAGE). These observations indicate that brain malformations in TSC are likely a consequence of increased TORC1 activation during embryonic brain development. We also provide evidence supporting the possible immunogenicity of giant cells and the early activation of inflammatory pathways in TSC brain.
