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

BACKGROUND/

objectivesCurrent measures of cytokines involve urine, blood or saliva which have drawbacks including circadian rhythm variations and complicated collection methods. Sweat has been used to measure cytokines in young and middle-aged adults, but not older adults. We sought to determine the feasibility of using sweat to measure cytokines in older adults compared to younger adults.

designTwo visit cross-sectional pilot study stratified by age group.

settingIndependent living facility and Johns Hopkins University both in Maryland.

participants23 community-dwelling adults aged 65 and older and 26 adults aged 18-40 were included. Those with active cancer treatment or with a known terminal illness diagnosis were excluded. MEASUREMENTS: Sweat interleukin-6 (IL-6), interleukin-10 (IL-10), and tumor necrosis factor-alpha (TNF-α) were collected using a non-invasive sweat patch worn for 72h by each participant. Samples were measured with a single molecule array (SIMOA) technology for ultrasensitive, multiplexed detection of proteins.

results23 older adults and 26 younger adults with mean ages of 77±8.0years and 28±5.5years, respectively, completed the study. Both groups had high rates of compliance with patch wearing and removal. Higher concentrations of TNF-α, IL-6 and IL-10 were observed in older adults compared to younger adults, which remained significant after controlling for race, sex, body mass index, and chronic disease count (0.110±0.030 vs. 0.054±0.020pg/mL, 0.089±0.012 vs. 0.048±0.018pg/mL, and 0.124±0.029 vs. 0.067±0.025pg/mL, respectively).

conclusionThese results suggest that sweat patches are a feasible method to collect cytokine data from older adults. Preliminary group differences in cytokine measurement between older and younger groups correspond with current literature that cytokines increase with age, suggesting that sweat measurement using the sweat patch provides a new method of exploring the impact of inflammation on aging. Further research using sweat and the sweat patch is recommended.
