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
objectiveTo comprehend the effects of diverse therapeutic interventions on thromboelastography (TEG) and conventional coagulation parameters among individuals diagnosed with colorectal cancer, this study aims to explore the clinical relevance of both thromboelastography and conventional coagulation metrics in evaluating coagulation function and predicting the incidence of thrombotic and hemorrhagic events in patients with colorectal cancer.
methodsA cohort of 122 patients with colorectal cancer retrospectively recruited and divided into 2 groups: those undergoing surgical intervention (operation group) and those not subjected to surgery (non-operation group). According to the different types of treatment they received, the operation group was divided into chemotherapy-only group and a group receiving a combination of targeted therapy and chemotherapy. Blood samples were collected on admission and subjected to coagulation parameter assessment, including conventional coagulation tests and thromboelastography (TEG) assessment. Receiver operating characteristic (ROC) analysis was performed to predict the occurrence of complications in patients with colorectal cancer.
resultsCompared with the operation group, the non-operation group showed significant reductions in reaction time(R-time) and kinetics time (K-time), and significant elevation in angle, maximum amplitude (MA), fibrinogen and platelets. Patients receiving targeted therapy and chemotherapy had lower angle and maximum amplitude and higher R-time and K-time, activated partial thromboplastin time and fibrinogen. The area under the curve for TEG in patients without treatment was 0.802. The area under the curve for TEG and conventional coagulation parameters were 0.654 and 0.660 respectively.
conclusionDiverse treatments distinctly impact on the coagulation indicators of individuals diagnosed with colorectal cancer. The coagulation parameters observed in patients prior to operation suggest a hypercoagulable state. Nevertheless, following postoperative chemotherapy and targeted therapy, this hypercoagulable state demonstrates a notable improvement, occasionally leading to a propensity for hypocoagulation. The findings of this investigation underscore the unique clinical importance of thromboelastography (TEG) alongside traditional coagulation parameters, demonstrating that these diagnostic tools possess complementary value and cannot be substituted interchangeably.
