GRADE*: study design, within study risk of bias, consistency of results, directness (generalizability), precision (sufficient data), reporting bias (publication, language, funding, other); open symbol= no benefit; closed symbol = beneficial; duration of effect noted by number of symbols: one = IP, two = ST, three = IT, 4 = LT; diamond (♦ or ◊) = high GRADE; dot (● or ○) = moderate GRADE with solid symbol indicating benefit and open symbol indication no benefit
Clinically Important is determined by considering the following factors: minimal detectable change, minimal clinically important difference (> 15%), large magnitude of effect measured by weighted mean difference, number needed to treat, absolute benefit &, treatment advantage, high dose response gradient, duration of the effect (IP – immediate post treatment, ST - short term for about 3 months, IT – intermediate term for about 6 months, LT – long term for about 1 year)
Key: WAD – whiplash associated disorder; IP – immediate post-treatment follow-up; ST – short-term follow-up; IT – intermediate-term follow-up; LT – long-term follow-up; SMDp – pooled standard mean difference; WMDp – weighted mean difference; RRp – pooled relative risk; M-A –meta-analysis; NNT – number-needed-to-treat; 95%CI – 95% confidence interval, † no significant difference between groups for this outcome, GPE – global perceived effect; VAS – visual analogue scale; QALY – quality of life years; PT – physiotherapy; CBT – cognitive behavioral training; NR – not reported; NA – not applicable, vs – verses.
