Associations between ultrasonographic masseter muscle thickness, sarcopenia and Eichner index in geriatric outpatients : a case control 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
objectivesThe aim of this study was to assess the associations between ultrasonographic masseter muscle thickness, sarcopenia and Eichner Index in outpatients over 60 years of age.
methodsParticipants who admitted to a geriatric outpatient clinic of a university hospital were included in this study. Comprehensive geriatric assessments were recorded. The European Working Group of Sarcopenia in Older People 2 criteria were used to evaluate sarcopenia and probable sarcopenia. Masseter muscle thickness (MMT) was measured bilaterally by ultrasonography. The sum of the mean MMT values for the right and left sides was divided into two equal parts, and the average of these two parts was recorded as the average MMT (AMMT). Masseter muscle was grouped into 3 types according to band appearances. State of dentition was evaluated according to the Eichner index.
results>Fourty-six participants whose median age was 73 were included in the study (19.6% probable sarcopenic, 30.4% sarcopenic). AMMT was significantly lower in those with high SARC-F scores compared to low SARC-F score group (p=0.041). AMMT, the distribution of Eichner groups, right and left masseter muscle fibriller types were similar in probable sarcopenia, sarcopenia and non-sarcopenic groups (p˃0.05). AMMT was significantly correlated with handgrip strength, appendicular skeletal muscle mass, calf circumference. Left-sided functional tooth units correlated positively with left MMT, whereas the Eichner index was not independently associated with sarcopenia.
conclusionsDecreased MMT might be useful as a predictor of low appendicular skeletal muscle mass.
