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
Hypoxia-mediated tumor progression is a major clinical challenge in human cancers including colorectal cancer (CRC). In addition, exosome-mediated transfer of miRNAs from cancer-associated fibroblasts (CAFs) to cancer cells could promote tumor progression. However, the mechanisms by which hypoxia CAFs promotes CRC progression remain largely unknown. CAFs and normal fibroblasts (NFs) were isolated from CRC tissues and adjacent normal tissues. Next, exosomes were isolated from the supernatant of CAFs that cultured under normoxia (CAFs-N-Exo) and hypoxia (CAFs-H-Exo). RNA-sequencing was then performed to identify differentially expressed miRNAs (DEMs) between CAFs-N-Exo and CAFs-H-Exo. Compared with exosomes derived from normoxia CAFs, exosomes derived from hypoxic CAFs were able to promote CRC cell proliferation, migration, invasion, stemness and reduce the sensitivity of CRC cells to 5-fluorouracil (5-FU). In addition, miR-200b-3p levels were dramatically decreased in exosomes derived from hypoxic CAFs. Remarkably, increasing exosomal miR-200b-3p in hypoxic CAFs reversed the promoting effects of hypoxic CAFs on CRC cell growth in vitro and in vivo. Furthermore, miR-200b-3p agomir could inhibit CRC cell migration, invasion, stemness and increase the sensitivity of SW480 cells to 5-FU via downregulating ZEB1 and E2F3. Collectively, loss of exosomal miR-200b-3p in hypoxia CAFs could contribute to CRC progression via upregulation of ZEB1 and E2F3. Thus, increasing exosomal miR-200b-3p might serve as an alternative approach for the treatment of CRC.
