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
Colorectal cancer (CRC) is a malignant digestive tumor associated with high mortality rate. Currently, 5-Fu therapy is a frequently used treatment approach for CRC. Yet, acquirement of 5-Fu resistance ultimately leads to therapeutic failure in CRC patients. LncRNA NOP14-AS1 was upregulated in cancers, but its biological functions and mechanisms in 5-Fu resistant colorectal cancer remain elusive. We discovered that NOP14-AS1 was high-expressed in colorectal tumors and cancer cells. Silencing NOP14-AS1 sensitized CRC cells to 5-Fu. By creating a 5-Fu resistant CRC cell line (HT-29 5-Fu R) and observed that expression of NOP14-AS1 was remarkedly elevated in 5-Fu resistant cells compared to parental cells. Additionally, we found that miRNA-30a-5p was a target of NOP14-AS1 and directly affected its function. miR-30a-5p overexpression sensitized CRC cells to 5-Fu treatment and targeted the glycolysis key enzyme, LDHA. Rescue experiments showed that restoring LDHA in CRC cells which were overexpressing miR-30c-5p successfully overridden 5-Fu resistance. Importantly, restoring miR-30a-5p in NOP14-AS1-overexpressing cells effectively restored 5-Fu sensitivity in HT-29 5-Fu R cells by targeting the LDHA-mediated glucose metabolism. In summary, our results revealed that lncRNA NOP14-AS1 promotes 5-Fu resistance by mediating the miR-30a-5p-LDHA axis.
