Hip arthroscopy in Sweden: a nationwide registry study of socioeconomic characteristics, regional variation, and sick leave patterns.
Article in Acta orthopaedica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 and purposeClinical outcomes are well described after hip arthroscopy (HA), but less is known about the demographic, socioeconomic, and work-related characteristics of individuals undergoing the procedure at a population level. We aimed to describe demographic, socioeconomic, and regional characteristics of individuals undergoing HA in Sweden based on nationwide registry data compared with an age- and sex-matched reference population, and to describe regional variation in the annual incidence of HA using nationwide registry data.
methodsWe conducted a nationwide descriptive registry study including all individuals aged 18-65 years who underwent HA in Sweden between 2006 and 2018. Each individual was matched by sex and year of birth to 5 reference individuals from the general population. National registers provided information on demographics, region of residence, education, citizenship, employment status, income, and compensated sick leave.
resultsThe study included 4,633 individuals undergoing HA and 23,060 matched reference individuals. Mean age was 36 years, and 3,019/4,633 (65%) were men. Residence-based HA incidence was highest in metropolitan and nearby counties. Individuals undergoing HA more often had post-secondary education (1,874/4,633 [40%] vs 8,003/23,060 [35%]), employment before surgery (4,299/4,633 [93%] vs 19,267/23,060 [84%]), and high-income levels (1,996/4,633 [43%] vs 7,358/23,060 [32%]) than the reference population. Compensated sick leave was more common among individuals undergoing HA both before surgery (741/4,633 [16%] vs 1,614/23,060 [7%]) and during the year after surgery (1,436/4,633 [31%] vs 1,845/23,060 [8%]).
conclusionIndividuals undergoing HA were more often employed and belonged to higher-income groups than a matched reference population. HA incidence varied substantially between regions, and individuals undergoing HA demonstrated higher levels of compensated sick leave both before and after surgery.
