Overactive Bladder Symptoms as a Predictor of Longitudinal Decline in Grip Strength in Community-Dwelling Men: A 4-Year Longitudinal Study.
Article in Lower urinary tract symptoms, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesLower urinary tract symptoms (LUTS) are associated with sarcopenia in men. However, it is not clear whether LUTS are related to the decline in physical function. We investigated the longitudinal association between the LUTS severity and the grip strength change in community-dwelling men.
methodsA 4-year longitudinal study was conducted using data from 151 men (median age 53 years) enrolled in the Iwaki Health Promotion Project. Grip strength change was calculated as the difference between 2015 and 2019 measurements. LUTS severity was assessed with the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS). Baseline variables included age, Aging Male Symptoms score, serum testosterone, albumin, interleukin-6, HbA1c, daily exercise, skeletal muscle mass index, and percent body fat. Correlations and multiple regression analyses were performed.
resultsThe median age and baseline grip strength were 53 years and 41.3 kg, respectively. Grip strength decreased significantly after 4 years, with a median value of -1.1 kg. There was a significant negative correlation between total OABSS, OABSS Q3 (frequency of urinary urgency, r = -0.234, p = 0.003), Q4 (frequency of urge urinary incontinence, r = -0.190, p = 0.020), and grip strength change, whereas the IPSS voiding symptoms domain was not. Multiple regression analysis showed that only the total score of OABSS Q3 and Q4 was significantly correlated with grip strength change (standardized β = -0.930, p = 0.012).
conclusionsThe main symptoms of OAB may be indicators of the grip strength decline in men.
