Correlation Between Thromboelastography and Standard Coagulation Tests at a Tertiary Community Hospital.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThromboelastography (TEG) assesses the clotting capacity of whole blood in real time, while standard coagulation tests (SCTs) represent static measures. Evidence of correlation between values obtained via TEG and SCTs remains scarce. The purpose of this study was to evaluate the correlation between TEG and SCT values and assess interventions received utilizing an institution-specific TEG algorithm. MATERIALS AND
methodsThis was a single-center retrospective chart review. Data were obtained using the TEG Manager® program and the EPIC® electronic medical record for adult patients ≥18 years admitted between July 2019 and September 2019. TEG values assessed included R-time, K-time, maximum amplitude (MA), and lysis at 30 minutes. SCT values assessed included PT/INR (prothrombin time/international normalized ratio), platelet count, fibrinogen, and hemoglobin/hematocrit. Descriptive statistics were used for the primary analysis. Spearman's coefficient was used for correlation analysis, with strong correlation defined as r>0.7.
resultsThe primary analysis included 100 patients, with a median age of 62.5 years (IQR 49.3-76.0) and 52% male. No strong positive correlations were identified between any TEG and SCT values. Twenty-two patients (22%) received a blood product, and six patients (6%) received a hemostatic agent, with the majority receiving platelets or four-factor prothrombin complex concentrate. An inappropriate intervention was identified in 30% of TEGs, of which 22 (61.1%) indicated a need for platelets due to a low MA angle without subsequent platelet administration.
conclusionsThe lack of strong positive correlations between TEG and SCT values was consistent with the existing literature. Further provider and pharmacist education is required to improve utilization of the institutional TEG algorithm.
