Epidemiology and disease burden of complex wounds for inpatients in China: an observational study from Sichuan province.
Observational study in BMJ open, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled 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.
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 investigate the period prevalence of complex wounds among the overall inpatients, and the impact of complex wounds on inpatient health expense and length of hospital stay (LOS).
designAn observational study.
setting6056 healthcare institutions across Sichuan province in China.
participantsThis study included 4 033 763 people admitted to healthcare institutions during 1 September 2018 and 31 December 2018.
resultsThe point prevalence of complex wounds was 4.07 per 1000 among inpatients in Sichuan. The most common complex wounds were pressure ulcers (1.47 per 1000 among inpatients). Older, male, Han ethnic groups and retired people were most likely to suffer from complex wounds. The median LOS was longer for those with complex wounds as their main condition of treatment compared with all-cause admissions in Sichuan (12 days compared with 7 days; p<0.001). The median cost of care for people with complex wounds was higher than for admission for any cause (¥6500.18 compared with ¥3337.16; p<0.001). People with pressure ulcers had the longest LOS, while people with ulcers related to diabetes incurred the highest costs.
conclusionsComplex wounds, especially pressure ulcers, are common in Sichuan province and their presence is associated with significantly longer lengths of hospital stay and higher medical costs. Additionally, this study only included admitted inpatients during the sampling time period, hence the prevalence of complex wounds may be underestimated. The high prevalence rate and heavy direct and indirect disease burden of complex wounds indicate that health policies for early detection and prevention of complex wounds in elders are urgently needed.
