Reported prevalence and risk factors of malignant tumors in the elderly population in China: a nationwide cross-sectional study.

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
backgroundMalignant tumors are one of the most challenging public health problems facing mankind. It is of great significance to systematically, comprehensively, and fully understand and analyze the prevalence and distribution of malignant tumors in the elderly population.
aimsTo evaluate the prevalence and associated factors of malignant tumors in the elderly population in China, and quantify the differences in prevalence and associated factors by urban and rural area, sex, and age.
methodThe data is based on Chinese citizens aged 60 and above, using a self-weighted sampling design of stratified, multi-stage, Probability Proportionate to Size Sampling (PPS), and equal-probability sampling at the end of the stage. The analysis included 224,142 valid questionnaires.
resultsAmong the 215,041 elderly people who participated in the survey, a total of 2,463 participants reported the diagnosis of malignant neoplasms, with a prevalence rate of 1.2%. Urban and rural areas, marital status, living alone, drinking, medical insurance, income, education level and economic status were associated with malignant tumors. Rural household registration, living alone, moderate alcohol consumption, without medical insurance and having income were associated with a lower prevalence of malignant tumors.
conclusionsThe prevalence of malignant tumors in urban residents is higher than that in rural residents. There was no significant difference in the overall prevalence of malignancies between sexes. Urban residence, not living alone, higher education level, and poor economic conditions were found to be associated with a higher prevalence of malignant tumors among the elderly, while widowhood and moderate alcohol consumption appeared to be associated with lower prevalence.They could inform future prevention strategies for malignancies and highlight unresolved health disparities.
