Effects of 12-week combined whole-body electric muscle stimulation and lower-extremity strength training on body composition, blood lipid levels, and isokinetic muscle function of patients with obesity and knee pain.
Article in Physical activity and nutrition, 2025. 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
purposeWe examined the effects of a 12-week combined treatment intervention consisting of whole-body electric muscle stimulation (WB-EMS) and lower-extremity strength exercise on body composition, blood lipid levels, knee pain, and functional ability of patients with obesity and knee pain.
methodsFourteen patients with obesity and knee pain were randomly assigned to a control group (CON; n = 7) that performed lower-extremity strength exercises and an experimental group (EXP; n = 7) that performed lower-extremity strength exercises combined with WB-EMS. All participants performed the exercise program three days a week for 12 weeks. The WBEMS current strength of the combined treatment was set to a subjective maximum endogenous strength level of 2,500-5000 Hz (medium frequency).
resultsThe CON and EXP groups showed similar improvements in body composition, blood lipid levels, Kellgren-Lawrence grading system, and functional ability. However, the Kujala patellofemoral score and isokinetic peak power of the quadriceps femoris improved more in the EXP group than in the CON group.
conclusionThe 12-week combined treatment intervention of WB-EMS and lower-extremity strength training applied in this study effectively improved pain and knee extension muscle strength in patients with obesity and knee pain.
