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.

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.

Abstract

Objective: To assess the efficacy of whole-body vibration (WBV) on hand grip strength, muscular activity, and upper limb function in young females with smartphone addiction. Materials and methods: This is a single-blinded randomized controlled trial. 66 females aged 18-25 years with smartphone addiction were randomly distributed into two equal groups; WBV group: It received WBV with strengthening exercises, and Sham WBV group: that received Sham WBV plus strengthening exercises. All participants received two sessions per week for four consecutive weeks. The primary outcome was hand grip strength. Secondary outcomes included pinch strength, muscle activity, and upper limb function. Evaluation was performed at baseline and after 4 weeks. Results: Post-treatment, there were significantly greater improvement in all variables with more favor to WBV group ( Conclusion: WBV combined with hand strengthening exercises might have a positive effect in enhancing hand grip strength, pinch strength, muscle activity, and upper limb function among young females with smartphone addiction. WBV could be a valuable adjunct to traditional rehabilitation programs targeting musculoskeletal effects of smartphone overuse. Clinical trial registration: ClinicalTrials.gov, identifier: NCT06849687.
