Urban versus rural differences of hip fractures among the elderly in Kyoto, Japan: a 10-year study.
Article in Archives of osteoporosis, 2021. 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
Secular changes in the incidence rate of hip fractures were estimated to vary by fracture type, i.e., femoral neck or trochanteric fractures, age, and sex, in urban or rural areas in Kyoto Prefecture, Japan from 2008 to 2017. PURPOSE: Our survey in Kyoto Prefecture from 2008 to 2017 showed that the incidence rate of femoral neck fractures is generally increasing. We investigated the differences between urban and rural areas in the changes of the incidence rate over time of femoral neck and trochanteric fractures during the same period.
methodsPatients aged 65 years and above who sustained hip fractures between 2008 and 2017 and were treated at one of the participating 11 hospitals were included. The ratio of sick beds for acute-term care at the investigated hospitals to total number of beds in the urban area was 16.5% (1863/11,158) and 30.6% (1863/5623) in the rural area. The change in incidence rate was estimated utilizing the population according to the national census conducted in 2010 and 2015.
resultsThere were 3559 and 6474 hip fractures in the urban and rural areas, respectively. Femoral neck fractures were 1936 (54.4%) and 2813 (43.5%) in each area. The increase of the population-adjusted numbers was marked by neck fractures in males, in both areas. In women, there was a significant increase in femoral neck fractures in the urban area in those aged 85 years and over. For trochanteric fractures, a significant increase was only found in women aged 65 to 74 years in the rural area.
conclusionA regional difference in the secular changes in incidence rate of hip fractures was found in women, not in men, mostly because neck fractures in women increased in the over 85 group in the urban area.
