Saxena 2016

Low risk of bias

Allocation concealed, sequence generation random and baseline characteristics does not reveal any imbalance between the two groups.

Low risk of bias

Double‐blinded study and neither the participants nor the treating physicians were aware of the allocation.

Low risk of bias

Data reasonably complete for all the included patients till hospital discharge,Though many of the enrolled patients were lost to follow up, it was balanced between the two groups. Hence, it seems that the result is not biased as reasons for lost to follow up does not differ significantly between the groups.

Low risk of bias

EEG was used to diagnose abnormal activity

Low risk of bias

Trial analysed as per a priori registered protocol.

Low risk of bias

Low risk across all domains
