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
backgroundNon-small cell lung cancer (NSCLC) is one of the most common forms of lung cancer. Circular RNAs (circRNAs) have been recognized that can be used as novel molecular markers for cancer therapy. Here, we attempted to identify the role of hsa_circRNA_0075048 (circ_0075048) in NSCLC.
methodsQuantitative real-time polymerase chain reaction (qRT-PCR) was performed to analyze the levels of hsa_circ_0075048, miR-1225-5p and high mobility group box-2 (HMGB2). Cell proliferation was detected by Cell Counting Kit 8 (CCK8) and 5-Ethynyl-2'-deoxyuridine (EdU) assays. Flow cytometry was used to detect apoptosis. Transwell assay was used to assess cell migration and invasion. Sphere formation ability was tested by cell pellet test. The protein expression levels were detected by western blot and immunohistochemistry. Dual-luciferase reporter assay, RNA-pull down and RNA immunoprecipitation (RIP) assays were used to verify the targeting relationships between miR-1225-5p and circ_0075048 or HMGB2. Mice tumor models were constructed to ascertain the effects of circ_0075048 on tumor growth in vivo.
resultsCirc_0075048 was increased in NSCLC tissues and cells. NSCLC cell proliferation, migration, invasion and sphere formation ability were decreased by circ_0075048 knockdown, and cell apoptosis was induced. Downregulation of miR-1225-5p recuperated the effects of circ_0075048 knockdown on NSCLC progression. The effects of miR-1225-5p on cell proliferation, apoptosis, migration, invasion and sphere formation were attenuated by HMGB2 overexpression.
conclusionThis study indicated that circ_0075048 played an oncogenic role in the development of NSCLC by regulating miR-1225-5p and HMGB2. The data provide more possibilities for the treatment of NSCLC.
