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
aimTo examine the association of muscle strengthening activities with knee extension strength, gait speed, and skeletal muscle index in adultsaged 50-64 and ≥65 years.
findingsMuscle strengthening activities are linked to better gait speed, knee extension strength, and skeletal muscle index mainly in middle-aged adults (50-64 years), with weaker or no associations in older adults except for higher activity frequency (≥8 sessions/month), benefi tingstrength in those ≥65 years. MESSAGE: Muscle strengthening activities are linked to better physical function and muscle health in middle-aged compared to older adults,although frequency may be a confounding parameter.
backgroundThis study examined the association of muscle strengthening activities (MSA) with knee extension strength (KES) and gait speed (GS) (n = 2169), and skeletal muscle index (SMI; n = 765) in adults aged 50-64 and ≥ 65 years.
methodsData were drawn from the National Health and Nutrition Examination Survey 1999-2018 cycles. MSA were self-reported based on engagement with weightlifting, push-ups, or sit-ups. MSA frequency was categorized as ≥ 8 or < 8 sessions/month. Linear and logistic regressions were performed, adjusting for demographic and clinical covariates.
resultsMSA were associated with improved GS and KES across adults aged 50-64 years in fully adjusted models (GS: β = -0.24, 95% CI - 0.42 to - 0.07; KES: β = 31.7, 95% CI 18.9 to 44.5) but not in those ≥ 65 years (GS: p = 0.07; KES: p = 0.11). For SMI, a significant positive association emerged only in the 50-64-year old group after adjustments (β = 0.18, 95% CI 0.03 to 0.34; ≥ 65 years → p = 0.53). Age interaction (≥ 65 vs. 50-64 years) showed significant MSA associations with GS and KES, though SMI results were inconsistent. Finally, higher MSA frequency for ≥ 65 versus 50-64 years was linked to higher KES (β = 22.0, p = 0.03), but not GS (p = 0.05) or SMI (p = 0.64).
conclusionsMSA are associated with higher KES and GS in middle-aged, but not in older adults. Higher MSA frequency is linked to increased KES in older adults.
