Long-term risk of venous thromboembolism following hip or knee replacement surgery: a population-based matched cohort study.

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: Hip or knee joint replacement (HJR or KJR) is linked to a short-term increased risk of venous thromboembolism (VTE), but evidence on long-term VTE risk beyond 1 year is limited. This study compared the 10-year VTE risk in HJR or KJR patients with the general population. Methods: We conducted a prospective matched cohort study using the UK Biobank. A total of 18,984 HJR and 16,709 KJR patients were matched with controls by age, sex, VTE history, and cancer history via exposure density sampling. Flexible parametric models and piecewise Cox models were used to estimate time-varying hazard ratios (HRs) and 95% confidence intervals (CIs) for VTE over 10 years postsurgery. Results: A total of 211,190 participants were included in the HJR cohort and 192,440 in the KJR cohort. The 10-year VTE risk was 6.2% (95% CI, 5.7%-6.7%) for HJR and 7.5% (95% CI, 7.0%-8.0%) for KJR. VTE risk peaked immediately postsurgery, declined gradually, but remained elevated throughout the 10-year follow-up. For HJR, the HR decreased from 24.10 (95% CI, 16.93-34.30) in the first 30 days to 1.49 (95% CI, 1.17-1.90) in years 8 to 10. For KJR, it decreased from 27.31 (95% CI, 19.67-37.92) to 1.32 (95% CI, 1.04-1.68) over the same period. Conclusion: VTE risk rises sharply after HJR or KJR and remains elevated for 10 years. Further studies should extend follow-up and collect detailed covariates related to VTE events to validate and characterize the potential long-term risk associated with HJR or KJR.
