Study characteristics
Methods	Parallel RCT Approved by the ethics committee and informed consents obtained Site: Tata Motors Hospital, Jamshedpur, Jharkhand, India Data collection: no information Funding: departmental/institutional Registration: no information
Participants	60 ASA I to II participants of both sexes, weight > 50 kg, scheduled for fracture femur operation under central neuraxial block but unable to sit because of pain Excluded: could sit comfortably; any contraindication to spinal anaesthesia, FNB, or local anaesthetic Type of fracture: neck femur fracture (N = 16), intertrochanteric femur fracture (N = 29), shaft femur fracture (N = 15) Anaesthetic technique for surgery: spinal block Surgical technique: not stated Mean age: 64.3 years (range 18 to 70 years) Percentage female: 33% Length of follow‐up: 5 minutes
Interventions	Intervention: femoral nerve block (N = 23 for proximal end femur fracture) Comparator: no nerve block (N = 21 for proximal end femur fracture)
Outcomes	Relevant to this review. Pain (at 5 minutes after block placement). Participant satisfaction (binary scale). Not relevant to this review. Haemodynamic variables. Pulse oximetry during spinal blockade. Time to perform spinal block. Quality of positioning. Rescue analgesia.
Notes	Conflict of interest: "none declared" DOI: 10.4103/0019‐5049.147146 Study also includes participants with shaft fracture. We obtained results for pain scores on movement for participants with proximal fracture only from the study authors. However, we did not keep results in the analysis (see Effects of interventions) owing to the short delay between the block and the evaluation Email sent on 5 January 2020 for additional information Sources obtained for risk of bias assessment.
