1 · What the graph read from it

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.

2 · The registry

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

backgroundThe preoperative prevalence of deep venous thromboembolism (DVT) of patella fracture is not well established. The study aimed to investigate the preoperative prevalence, the associated risk factors, and the locations of deep venous thrombosis (DVT) in patients with closed patella fracture.

methodsPatients who sustained closed patella fracture between January 1, 2016, and April 1, 2019, were included. Blood analyses and ultrasonography of bilateral lower extremities were routinely performed. Data of demographics, comorbidities, mechanism of injury, fracture type, total hospital stay, time from injury to DVT, and laboratory indexes were prospectively collected and compared between groups with and with non-DVT. Multivariate logistic regression analyses were performed to determine the independent risk factors of DVT.

resultsAmong the study cohort of 790 patients, 35 cases occurred in preoperative DVTs, indicating a prevalence of 4.4%, with 3.2% distal and 1.2% proximal DVT. Age ≥ 65 years old (OR, 3.0, 95% CI, 1.1-8.1), D-dimer > 0.5 mg/L (OR, 2.3, 95% CI, 1.1-4.8), and albumin < 35 g/L (OR, 2.5, 95% CI, 1.2-5.3) were identified to be risk factors of DVT in closed patella fracture. Among the DVTs, 30 cases (85.7%) occurred in the injured extremity, 3 cases (8.6%) in bilateral extremities, and 2 cases (5.7%) solely in the uninjured extremity.

conclusionThe prevalence of preoperative DVT in closed patella fracture was 4.4%, with 3.2% for distal and 1.2% for proximal DVT. We recommend individualized risk stratification and early anticoagulation for patients with risk factors (age ≥ 65 years, D-dimer > 0.5 mg/L and albumin < 35g/L).
