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

purposeUltrasound is a bedside assessment tool used in some medical specialties. Studies have used this modality for the assessment of the skeletal muscle in hospitalized older patients for whom functional tests and imaging assessment by magnetic resonance imaging and computed tomography are not feasible. This study aimed to investigate whether skeletal muscle thickness (MT) and echo intensity (EI) obtained via ultrasonography are parameters for detecting the risk of malnutrition and physical conditions in acutely hospitalized older patients.

methodsFifty-nine men and women (31 men, 28 women; 84.4 ± 5.7 years) hospitalized for acute care were included. B-mode ultrasonographic images were obtained within 1 week of admission. MT and EI were measured in the rectus femoris (RF), vastus lateralis (VL), and vastus intermedius (VI) muscles. We utilized the Mini Nutritional Assessment-Short Form (MNA-SF), handgrip strength, calf circumference, the Barthel Index (BI), instrumental activities of daily living (ADL) scale, and the clinical frailty scale (CFS) to determine malnutrition and physical conditions in the participants.

resultsStepwise regression analysis showed that the MNA-SF, BI, IADL, handgrip strength, calf circumference, and CFS scores were explained by MT in the VL and EI in the VI and RF (adjusted R

conclusionThese results suggest that the MT and EI in the quadriceps may reflect malnutrition risk and physical conditions in acutely hospitalized older patients.
