Epidemiology of cruciate ligament surgery in Japan: A repeated cross-sectional study from 2014 to 2021.
Article in PloS one, 2023. 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
Understanding the incidence and trends of cruciate ligament (CL) surgeries in Japan is crucial for providing effective healthcare services. This study aimed to use open data available from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) to analyze changes in CL surgeries over time and the characteristics of the Japanese population by sex and age. We retrospectively identified CL surgeries of the knee joint registered from April 2014 to March 2022 using the NDB open data. Data on sex, age, and practice were extracted to determine the number of cases per 100,000 population. Trends in the annual incidence of CL surgeries were evaluated using Poisson regression analysis. A total of 142,931 CL surgeries were performed from 2014 to 2021, with arthroscopic ligament reconstruction accounting for 98% of cases. The number of surgeries significantly increased from 16,975 in 2014 to 19,735 in 2019 (P<0.001). CL surgeries were most common in the 15-19 and 20-29 years age groups, with variations between males and females. The incidence of CL surgery in Japan has increased, with characteristics varying by sex and age, including middle-aged and older patients. Further investigation of general patterns in CL surgery in Japan would be valuable.
