Grasping rehabilitation using motor imagery with or without neurofeedback after tetraplegia: a study protocol for a bicentric randomised controlled trial.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03190863 (Investigating the Effect of Motor Imagery With or With no Visual Neurofeedback on Grasping Capabilities After C6-C7 Tetraplegia), which is not on this map.

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.

Abstract
introductionTetraplegia causes extensive sensorimotor deficits affecting activity, participation and quality of life. People with C6-C7 tetraplegia can learn to grasp objects by performing wrist extension movement (ie, tenodesis grasp), and motor imagery (MI) added to rehabilitation significantly improved tenodesis grasp. We hypothesise that this improvement can be further boosted by adding neurofeedback during MI. Thus, we design a randomised controlled trial investigating the effect of MI training on grasping ability in people with C6-C7 tetraplegia. METHODS AND ANALYSIS: We will perform a bicentric, assessor-blinded, randomised controlled study. During rehabilitation, 21 inpatients with C6-C7 tetraplegia will be allocated to MI with neurofeedback (MI training with graphical display on a computer screen based on mu (8-13 Hz) and beta (18-25 Hz) frequency rhythms measured with 32-channel electroencephalography), MI alone (only MI training) and control (watching movies and visualisation of geometric shapes). All participants will receive three 45-min training sessions per week for 5 weeks.The primary outcome measure will be wrist extension angle immediately after the intervention during tenodesis grasp measured with a 3D motion analysis system (VICON). Secondary outcomes will include a range of measures: kinematic, grip strength, upper limb range of motion, upper limb strength (manual muscle test and hand-held dynamometer measure), dexterity (box and block test, 9-hole peg test, Jebsen test, capabilities of upper extremity questionnaire), quality of life (WHOQOL-Bref), daily life autonomy (Quadriplegic Index of Function), MI capacity and brain reorganisation (magnetoencephalography only available in Lyon, n=15). We will measure all outcomes five times: during weeks 1, 3 and 5 (baseline), week 11 (immediately after the intervention end) and week 18 (8 weeks after the intervention end). ETHICS AND DISSEMINATION: Ethical approval was granted on 29 September 2017 (CPP Nord-Ouest-IV 17/25, N°2017-A00990-53). Dissemination will occur via presentation of results in scientific meetings and publication in peer-reviewed academic journals. TRIAL REGISTRATION NUMBER: NCT03190863 (ClinicalTrials.gov).
