1 · What the graph read from it

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.

2 · The registry

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

objectivesTo access the epidemiological characteristics of elderly people using emergency medical services (EMS) in Beijing, as a consequence of injurious falls, and the association between an ageing population and injurious falls.

designA longitudinal observational study based on Beijing EMS data.

settingAll citizens aged 60 years or above who used EMS from 2010 to 2017 in Beijing, China.

participantsDuring 2010 to 2017, 2516 128 people used EMS in Beijing. Of these, 1528 938 people aged under 60 years were excluded and the remaining 987 190 people were included in our study.

methodsData were from the emergency dispatch database of Beijing's Emergency Medical Centre. We described the proportion of elderly people using EMS in Beijing due to injurious falls with regard to region, time, sex, age and proportion of the elderly population.

resultsAmong the 987 190 participants who used EMS, 82 694 (8.38%) had had a fall. The proportion of falls rose from 7.12% in 2010 to 9.45% in 2017, and was higher in urban (8.62%) than in suburban (7.80%) regions. Elderly people were more likely to use EMS due to injurious falls during September to November (8.99%) than during December to February (7.68%) (adjusted OR (aOR)=1.19), and during 08:00 to 09:59 (10.02%) than during 00:00 to 01:59 (4.11%) (aOR=2.52). Elderly people in districts with high (8.92%, aOR=1.15) and medium (8.23%, aOR=1.09) proportions of an elderly population were more likely to use EMS due to injurious falls than those in districts with a low proportion of elderly population (7.81%).

conclusionsIn Beijing, the proportion of elderly people using EMS due to injurious falls increased with age, and was positively correlated with the proportion of the elderly population. Taking care of elderly people and preventing injurious falls should be one of the key issues to be handled in a society with an ageing population.
