Increased complications of proximal femur fractures during the COVID-19 pandemic: a nationwide medical claims database study in Japan.
Article in Journal of bone and mineral metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
introductionCoronavirus disease 2019 (COVID-19) is a worldwide pandemic, and mortality increases in elderly patients with comorbidities. This study aims to examine the in-hospital complications and mortality for elderly patients with proximal femur fractures during the COVID-19 pandemic or countermeasure periods. MATERIALS AND
methodsThe proximal femur fractures undergoing surgery during the COVID-19 pandemic or countermeasure period were compared with the pre-pandemic in a Japanese national inpatient data. The assessed outcomes were the development of pneumonia, deep vein thrombosis (DVT), pulmonary embolism (PE), and mortality during hospitalization in two periods, and those for COVID-19-positive patients.
resultsA total of 284,922 proximal femur fractures aged over 65 years were included. In the COVID-19 pandemic period compared to the pre-pandemic, the odds of pneumonia, DVT, PE, and mortality decreased to 0.942 (95% confidence interval [CI]: 0.901 - 0.986, P = 0.0102) and 0.839 (95% CI: 0.745 - 0.946, P = 0.004), increased to 1.153 (95% CI: 1.112 - 1.195, P < 0.001), and 1.048 (95% CI: 0.982 - 1.118, P = 0.1554), respectively. For COVID-19 positivity at admission, the odds of PE increased significantly to 12.95 (95% CI: 8.795 - 19.06, P < 0.001). For COVID-19 positivity during hospitalization, the odds of pneumonia and mortality were increased to 2.896 (95% CI: 1.820 - 4.608, P < 0.001) and 6.303 (95% CI: 3.440 - 11.55, P < 0.001), respectively.
conclusionThese findings alert healthcare professionals and patients to the elevated complications, especially PE rate for proximal femoral fracture with COVID-19 positive.
