Support for judgement | Review authors' judgement | |
Selection bias: Random sequence generation | Method not described. Not randomized choice | High bias probability |
Selection bias: Allocation concealment | Recall of patients treated some years before, with similar characteristics, in 2006 for needling plus corticost inj and in 2008 only for needling | High bias probability |
Performance bias | No blinding of the patient referred to the treatment is described | High bias probability |
Detection bias | No blinding of outcome assessors is described | High bias probability |
Attrition bias | No patients outcomes attrition or exclusion are described. All the patient who received the procedure have an outcomes reported |
Low bias probability |
Reporting bias | No selective outcomes reporting are present | Low bias probability |
Other sources of bias | No | Low bias probability |
