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

Fibroblasts (Fibs) contribution to neoplastic progression, tumor growth, angiogenesis, and metastasis has been recently reported by several research groups. In this study it was investigated if fibroblasts are the source of brain-derived neurotrophic factor (BDNF), which plays a crucial role in the progression of oral squamous cell carcinoma. In a novel in vitro system oral Fibs were cultured with SCC-25 lingual squamous cell carcinoma cells for 7days. Factors related with this interaction were investigated by quantitative PCR and western blot. In the co-culture, fibroblasts were converted to carcinoma-associated fibroblasts (CAFs), which in return initiated epithelial-mesenchymal transition (EMT) of SCC-25 cells. The induced CAFs produced increased levels of BDNF, which interacted with the increased-expressed neurothrophin receptor B (TrkB) on EMT-converted SCC-25 cells. Possible regulatory factors of BDNF expression (tumor necrosis factor-α and interleukin-1-β) were detected both in CAFs and EMT-tumor cells. In CAFs: IL-1β-, in SCC-25 cells TNF-α-gene-expression was significantly increased in co-culture conditions. Activated fibroblasts (CAFs) and mesenchymal transitioned tumor cells might use the BDNF-TrkB axis and its regulation to harmonize their interaction in the process of tumor progression.
