Table 3 Post-test probability of a fall in patients classified as high risk (≥13.5 seconds) and low risk (<13.5 seconds) using the TUG score

From: Is the Timed Up and Go test a useful predictor of risk of falls in community dwelling older adults: a systematic review and meta- analysis

Application of TUG test Pre test probability (%) + LR (95% CI) Post test probability (%) + LR -LR (95% CI) Post test probability (%) -LR
All studies 51% (49%-53%) 1.20 (0.82-1.75) 56% (54%-58%) 0.93 (0.78-1.10) 49% (47%-51%)
Studies where TUG was administered as fast as possible excluded 52% (49%-54%) 1.53 (1.31-1.79) 62% (59%-64%) 0.79 (0.62-1.01) 46% (44%-48%)
Studies with duration of follow up > or < one year excluded 53% (51%-56%) 1.11 (0.64-1.92) 56% (54%-59%) 0.95 (0.73-1.24) 52% (50%-55%)
Studies with selection bias excluded 52% (50%-55%) 0.81 (0.40-1.16) 47% (45%-50%) 1.10 (0.72-1.71) 54% (52%-57%)
Studies with unclear/no details on index test excluded 56% (54%-58%) 1.14 (0.67-1.91) 59% (57%-61%) 0.95 (0.74-1.21) 55% (53%-57%)
Studies with unclear/no definition ‘fall’ excluded 54% (51%-56%) 1.50 (1.15-1.94) 64% (61%-66%) 0.89 (0.75-1.04) 51% (48%-53%)
