Use of Placebo Surgery in Controlled Trials of a Cellular-Based Therapy for Parkinson's Disease
Abstract
Surgical procedures are frequently introduced into general practice on the basis of uncontrolled studies that are less rigorous than those required for the approval of medical interventions.1 The standard for the evaluation of surgical therapy is lower because of the complexity of designing and conducting scientifically valid and ethically acceptable clinical trials of surgical procedures.2 As a result, many surgical trials fail to control for investigator bias or placebo effects.3,4 The list of inadequately studied invasive or surgical procedures that became part of standard medical practice only to be abandoned after closer scrutiny includes bloodletting, routine tonsillectomy, routine circumcision, . . .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
