A recent study has revealed that patients who undergo a neurosurgical procedure with surgical start times between 9 pm and 7 am, are at an increased risk of developing complications compared to patients with a surgical start time earlier in the day. The analysis demonstrated that a patient's odds of having a surgical complication increased significantly between 9 pm and 7 am even after accounting for whether the case was an emergency versus elective procedure or if the patient had co-morbid conditions.

When accounting for the length of the surgery, the odds of a complication more than doubled. In the light of above can surgeries performed in late hours have more complications?
