  1. Legend: x: yes, (x): partially with general remarks, no: no/unclear. Item 1, sufficient description of question/objective; 2, appropriate study design; 3, appropriate method of participant selection or source of information/input variables; 4, sufficient description of patient characteristics; 5, report of means of assessment with outcome measures well defined and robust to measurement/misclassification bias; 6, appropriate sample size; 7, appropriate analytic methods and method description; 8, report of estimate of variance in main results; 9, control for confounding; 10, sufficiently detailed report of results; 11 conclusions supported by the results. Specifications: 1: clearly description, mention of specific gait parameters (no generalization e.g. gait changes), 2 / 3: precise information of in- and exclusion criteria and recruitment, 4: specific baseline characteristics of population (older people) must include: age, distribution male/female, global cognition, BMI or height/weight, number of medications or chronic disease/comorbidities, and for healthy older people: TuG, SPPB or comparable test of physical abilities, 5: Primary and secondary outcome must be clearly described. Error of measurement must be discussed, 6: sample size calculation should be reported 8: Means and estimate of variance (SD or IQR) must be reported for main outcome
