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
Background: To evaluate the effect of magnetic resonance imaging (MRI)-detected extramural vascular invasion (mrEMVI) and tumor deposits (TDs) on distant metastasis and long-term survival after surgery for stage III rectal cancer based on the relationship between the bottom of the tumor and peritoneal reflection. Methods: A retrospective study was performed on 694 patients who underwent radical resection for rectal cancer at the Harbin Medical University Tumor Hospital from October 2016 to October 2021. According to the surgical records, a new group was established based on the relationship between the lower end of the tumor and peritoneal reflection. On the peritoneal reflection group: the tumors are all located on the peritoneal reflection. Across the peritoneal reflection group: the tumors recurred across the peritoneal reflection. Under the peritoneal reflection group: the tumors are all located under the peritoneal reflection. We evaluated the effects of mrEMVI and TDs on postoperative distant metastasis and long-term survival of stage III rectal cancer by combining mrEMVI with TDs. Results: In the whole study population, neoadjuvant therapy (P=0.003) was negatively correlated with distant metastasis after rectal cancer surgery. Also, mesorectal fascia (MRF) (P=0.024), postoperative distant metastasis (P<0.001), and TDs (P<0.001) were independent risk factors for long-term survival after rectal cancer surgery. Lymph node metastasis (P<0.001) and neoadjuvant therapy (P=0.023) were independent risk factors for the presence or absence of TDs of rectal cancer. In the non-neoassisted subgroup, postoperative distant metastasis (P<0.001) was considered to be an independent risk factor for long-term survival after rectal cancer surgery. Conclusions: In the under the peritoneal reflection group, the combination of mrEMVI and TDs seems to play a certain guiding role in predicting distant metastasis and long-term survival after rectal cancer surgery.
