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

objectiveAnaemia leads to poor health outcomes in older adults; however, most current research in China has focused on younger adults. This study aimed to investigate the prevalence of anaemia and its associated factors in older adults in an urban district in China.

designA cross-sectional study.

settingAn urbanised region, Shenzhen, China.

participantsA total of 121 981 participants aged ≥65 years were recruited at local community health service centres in Shenzhen from January to December 2018. PRIMARY OUTCOMES: The prevalence of anaemia was analysed and potential associated factors were evaluated.

resultsThe mean haemoglobin level was 136.40±16.66 g/L and the prevalence of anaemia was 15.43%. The prevalences of mild, moderate and severe anaemia were 12.24%, 2.94% and 0.25%, respectively. Anaemia was positively associated with older age, being underweight (adjusted OR (AOR) 2.06, 95% CI 1.93 to 2.20), diabetes (AOR 1.23, 95% CI 1.19 to 1.28) and chronic kidney disease (AOR 1.41, 95% CI 1.36 to 1.46), and inversely with higher education level, current-smoker (AOR 0.84, 95% CI 0.78 to 0.89), non-habitual drinker (AOR 0.86, 95% CI 0.81 to 0.92), habitual drinker (AOR 0.81, 95% CI 0.75 to 0.87), overweight (AOR 0.67, 95% CI 0.64 to 0.70), obesity (AOR 0.57, 95% CI 0.53 to 0.61), central obesity (AOR 0.86, 95% CI 0.82 to 0.89), hypertension (AOR 0.86, 95% CI 0.83 to 0.89) and dyslipidaemia (AOR 0.81, 95% CI 0.78 to 0.84).

conclusionAnaemia is prevalent among people aged 65 years and older in China. Screening of high-risk populations and treatment of senile anaemia should be a top priority in Shenzhen, and should be listed as important public health intervention measures for implementation.
