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
backgroundNintendo Ring Fit Adventure (RFA) is a non-immersive exergame involving dynamic, whole-body movements. It provides a gamified alternative to conventional therapy, potentially promoting functional motor adaptations. This study aimed to investigate the effects of RFA on lower-limb bilateral asymmetry and maximum joint angles in female patients with chronic nonspecific low back pain (CNLBP) during obstacle crossing.
methodsThis study employed a randomized crossover trial. Twenty female patients with CNLBP were randomly assigned to receive both Switch Training (SWI) and Traditional Training (TRA) in a counterbalanced sequence. During the tests, participants crossed obstacles at three different heights (30%, 20%, and 10% of leg length (LL)). Kinematic data were collected using a 10-camera motion capture system, and ground reaction forces were recorded using three force platforms. Bilateral gait asymmetry indices and maximum joint angles of the lower limbs were calculated for each trial. A two-way repeated-measures ANOVA (2 × 3 design) was conducted to assess the effects of training condition (SWI and TRA) and obstacle height (30%, 20%, 10% of LL) on these parameters.
resultsWhen crossing obstacles at heights of 30% and 20% of LL, the SWI group showed lower swing time (SW) (left: P30% = 0.001, P20% < 0.001; right: P30% < 0.001, P20% = 0.004), stance time (ST) (left: P30% < 0.001, P20% < 0.001; right: P30% = 0.001, P20% = 0.004), and swing time/stance time (SW/ST) (left: P30% < 0.001, P20% < 0.001; right: P30% < 0.001, P20% < 0.001), and lower maximum angles of the hip and knee joints (all P < 0.05) than the TRA group. However, there were no significant differences in bilateral asymmetry or maximum joint angles between the SWI and TRA groups when crossing obstacles at 10% of LL (all P > 0.05).
conclusionsNintendo RFA training improved lower-limb asymmetry and movement patterns in female patients with CNLBP when crossing higher obstacles (30% and 20% of LL), reflected by reduced temporal parameters and joint angles. These improvements may contribute to safer obstacle-crossing performance.
