Conclusions : Neck pain was not significantly associated with high job dem and s , low skill discretion , low decision authority , or low peer support .
However , when these variables were combined with increased duration of computing tasks , or ergonomic dem and s , they reached significance .
Supervisor support was found to be the only significant buffer capable of preventing these variables reaching significance in female office workers
Introduction : The purpose of this systematic review was to examine literature on workplace factors associated with  neck pain or symptoms in computer users performing clerical functions .
ROBINS-I: a tool for assessing risk of bias in non-randomised studies of interventions
Non-r and omised studies of the effects of interventions are critical to many areas of healthcare evaluation , but their results may be biased . It is therefore important to underst and and appraise their strengths and weaknesses . We developed ROBINS-I ( “ Risk Of Bias In Non-r and omised Studies - of Interventions ” ) , a new tool for evaluating risk of bias in estimates of the comparative effectiveness ( harm or benefit ) of interventions from studies that did not use r and omisation  to allocate units ( individuals or clusters of individuals ) to comparison groups . The tool will be particularly useful to those undertaking systematic review s that include non-r and omised studies
