Clinical Profile of Patients Admitted With Venous Thrombosis to a Tertiary Care Hospital in India.

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 AND
objectivesVenous thrombosis is a frequent cause of hospitalization worldwide; however, data describing its clinical profile in Indian patients, particularly from hilly regions, remain limited. The present study aimed to describe the clinical profile of patients admitted with venous thrombosis to the medical wards of a tertiary care hospital in Himachal Pradesh, India. Additionally, we examined the prevalence of elevated D-dimer levels across different venous thrombosis sites and assessed the proportion of patients with confirmed deep vein thrombosis (DVT) and pulmonary embolism who would have been retrospectively classified as "likely" using the modified Wells criteria.
methodsThis cross-sectional observational study was conducted over a one-year period. All adult patients admitted with clinically suspected and radiologically confirmed venous thrombosis who met the inclusion and exclusion criteria were included. Clinical characteristics were described, and the prevalence of elevated D-dimer levels across different venous thrombosis sites was assessed. The modified Wells pre-test probability scores were applied retrospectively to patients with confirmed DVT and pulmonary embolism to determine the proportion classified as "likely."
resultsA total of 76 patients admitted with venous thrombosis were enrolled in the study. The mean age of the patients was 47.4 ± 16.3 years, and the female to male ratio was 1.3:1. Most patients had DVT (64.5%) (n=49) followed by pulmonary thromboembolism (PTE) (15.8%) (n=12) and cerebral venous thrombosis (CVT) (11.8%) (n=9) either as an isolated event or in combination with other venous thrombosis. Out of 49 DVT patients, the left lower limb was most commonly affected (75%) (n=36), and the most common presentation was limb swelling (95.9%) (n=47). The most common vessel involved was the femoropopliteal vein (38.8%) (n=19). Elevated D-dimer levels were observed in 91.8% (95% CI, 80.4-97.73%), 88.9% (95% CI, 51.75-99.72%), 100% (95% CI, 73.54-100%), and 81.82% (95% CI, 48.22-97.72%) of patients with DVT, CVT, PTE, and other thrombosis sites, respectively. When the modified Wells scores were applied retrospectively, 46 of 49 patients with DVT (93.9%; 95% CI: 83.13-98.72%) were classified as "Likely DVT" (score ≥2), while three patients (6.1%) were classified as "Unlikely DVT". Among the 12 patients with PTE, 11 patients (91.7%; 95% CI: 61.52-99.79%) were classified as "Likely PTE" according to the modified Wells criteria.
conclusionVenous thrombosis was a common cause of admission, with isolated DVT being the most frequent presentation, followed by PTE and CVT. Smoking and malignancy were commonly observed in this cohort, reflecting their prevalence rather than independent risk associations. Most patients with confirmed DVT and PTE would have been retrospectively classified as "likely" by the modified Wells criteria; however, this represents case-based classification and not validation of the model. Further prospective studies are needed to evaluate diagnostic tools and risk factors.
