Joint association of low muscle mass and mild anemia with all-cause, cardiovascular and cancer mortality among US middle and older adults.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLow muscle mass (LMM) and mild anemia (MA) are prevalent yet often overlooked conditions in middle-aged and older adults, each independently associated with adverse health outcomes. However, evidence regarding their combined effect on mortality remains limited. This study aimed to investigate the joint association of LMM and MA with all-cause, cardiovascular, and cancer mortality in a national sample of U.S. adults.
methodsWe analyzed data from 10,313 participants aged 45 years and older from the National Health and Nutrition Examination Survey (NHANES) 1999-2006 and 2011-2018, with mortality follow-up through December 2019. LMM was defined using appendicular skeletal muscle mass index (ASM/BMI), and MA was classified based on hemoglobin levels according to WHO criteria. Multivariable Cox proportional hazards models were used to assess individual and joint associations, adjusting for sociodemographic, lifestyle, and clinical factors.
resultsOver a median follow-up of 15.3 years, individuals with both LMM and MA had significantly elevated risks of all-cause (HR = 2.43; 95% CI: 1.82-3.26), cardiovascular (HR = 3.57; 95% CI: 2.31-5.52), and cancer mortality (HR = 3.86; 95% CI: 2.22-6.71) compared to those with neither condition. Significant additive and multiplicative interactions were observed between LMM and MA. Subgroup analyses revealed that the combined effect on cancer mortality was particularly pronounced in males and adults aged 65 years or older.
conclusionsThe co-occurrence of LMM and MA is strongly associated with increased risks of all-cause, cardiovascular, and cancer mortality among middle-aged and older adults. These findings highlight the importance of integrated screening and management of both conditions to mitigate mortality risks.
