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
Gastric cancer is one of the most common malignant tumors in the world. The occurrence of chemotherapy resistance seriously affects the survival and prognosis of middle and advanced patients. Enhancing DNA repair ability is one of the important mechanisms of chemotherapy resistance. ADAM9, a member of the disintegrin and metalloproteinase family, is involved in many biological processes, such as tumor cells proliferation, apoptosis, invasion and migration, vascular invasion, and drug resistance. In this study, we found that the high expression of ADAM9 in gastric cancer tissues was associated with a variety of clinicopathological factors and poor prognosis in patients. Gastric cancer cells with high ADAM9 expression reduced sensitivity to Cisplatin, decreased DNA damage, increased expression of ATM and CHK2, the key proteins in DNA damage repair pathway, and improved cancer cells survival rate. Further studies showed that the expression of ADAM9 was selectively interfered with gastric cancer cells, the expression levels of ATM and CHK2 were decreased, while the expression of damage protein γ-H2AX was significantly increased, the degree of DNA damage was increased, and the sensitivity of gastric cancer cells to Cisplatin was significantly enhanced. It is suggested that ADAM9 is involved in Cisplatin resistance in gastric cancer cells, and its mechanism is related to the activation of ATM-CHK2 pathway in DNA damage repair. These data demonstrate that ADAM9 plays a pro-cancer role and mediates Cisplatin resistance in gastric cancer, which may be a new target to overcome chemotherapy resistance.
