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 registryThe 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.

6 · The paper itselfAbstract
objectivesThis study aims to investigate the associations between dietary branched-chain amino acids (BCAAs) intake and appendicular skeletal muscle mass (ASM) as well as handgrip strength in Chinese adults.
methodsA total of 36,086 observations (54.32 ± 14.63 y) were included from the China Health and Nutrition Survey (CHNS) across three waves (2015, 2018, and 2022-2024). ASM was measured by bioelectrical impedance analysis, and handgrip strength was measured using a digital dynamometer. Dietary BCAA intake was assessed using three consecutive 24 h dietary recalls and adjusted for energy intake. Multilinear mixed-effect models were employed to examine the longitudinal association between BCAA intake and ASM. Multivariable regression was used to assess the cross-sectional association between BCAA intake and handgrip strength.
resultsDietary BCAA intake was significantly associated with ASM (β = 0.074,
conclusionsDietary BCAA intake is recommended to maintain muscle mass and strength in Chinese adults.
