Venous Thromboembolism Risk Assessment in Inpatient and Ambulatory Otolaryngology Surgical Patients.
Article in The Laryngoscope, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesVenous thromboembolic events (VTEs) are a leading cause of postoperative morbidity, prolonged hospital stay, and increased cost. Recommendations for mechano- and chemoprophylaxis are currently based on the 2005 Caprini score, a screening tool developed to identify patients at risk for VTE. The Caprini risk assessment model (RAM) was designed for surgical impatients and has been tested in a number of surgical fields, including otolaryngology. However, the vast majority of otolaryngology cases are performed as ambulatory surgery. Simpler RAMs include the COBRA scoring system and Pannucci-NSQIP. Here, we evaluate risk stratification of otolaryngology surgical patients and correlate the findings of these three RAMs. STUDY
designRetrospective chart review.
methodsA retrospective chart review of 869 patients undergoing surgery by Weill Cornell faculty otolaryngologists between June and December 2022 was performed. Patient demographics, VTE risk factors, admission status, surgical subservice, and postoperative events were collected, and RAM scores were calculated for each patient. Wilcoxon and Kruskal-Wallis rank-sum tests were utilized to assess differences in VTE risk scores based on type of procedure and admission status, and Spearman's correlation was utilized to assess agreement between the three different scoring systems. Multivariate linear regressions were utilized to assess variables that impacted the Caprini, COBRA, and NSQIP RAMs.
resultsIn total, two patients developed postoperative venous thromboembolism. Furthermore, there is a strong positive correlation between Caprini and COBRA RAMs (even when broken down by admission status, although it weakens in the inpatient population). There is a moderate positive correlation between Caprini and Pannucci-NSQIP in the full cohort, but that correlation is lost in the inpatient population.
conclusionsOtolaryngology surgical patients are at low risk of postoperative VTE. Caprini, Pannucci-NSQIP, and COBRA RAMs correlate well in determining ambulatory patients at risk for postoperative VTE and shorter, simpler RAMS such as COBRA and Pannucci-NSQIP can be used instead of Caprini RAM.
