The long-term risk of venous thromboembolism following bariatric surgery.

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
backgroundVenous thromboembolism (VTE) is a leading cause of morbidity and mortality following bariatric surgery. The exact duration and magnitude of post-surgery risk for VTE, however, is unclear. We analyzed a large administrative database to determine the long-term risk and predictors for VTE in patients undergoing bariatric surgery.
methodsA private insurance claims database was used to identify 17,434 patients who underwent bariatric surgery. Longitudinal data were available for each patient for up to 12 months post-surgery. We used logistic regression to identify independent predictors for VTE events.
resultsThe incidence of VTE during the index surgical hospitalization was .88%. This cumulative rate rose to 2.17% at 1 month and 2.99% by 6 months post-surgery. Over 74% of VTE events occurred after discharge. Risk factors identified for VTE developing by 6 months post-surgery included male sex (odds ratio (OR) = 1.68; confidence limits (CL) = 1.37-2.07), age ≥ 55 years (OR = 2.18; CL = 1.56-3.03), smoking (OR = 1.86; CL = 1.06-3.27), and previous VTE (OR = 7.48; CL = 5.78-9.67). The laparoscopic adjustable gastric band was less likely to result in VTE compared to open or laparoscopic gastric bypass (OR = .31; CL = .13-.75).
conclusionsThe period of increased risk for VTE following bariatric surgery extends well beyond the initial hospital discharge and 30 days after surgery. The high frequency of VTE up to 6 months following bariatric surgery suggests that more aggressively extended prophylaxis should be considered in patients at higher risk for VTE.
