Human Factors
I inadvertently pushed back from the gate without a final Dangerous Goods summary because I mistook a secondary planned summary to indicate that no Hazmat was loaded. Another reason that I hastily made my assumption was because we don't ever receive secondary planned DG summaries. We only get a final summary after the initial planned summary. Thankfully; due to ramp congestion; we did receive a final Dangerous Goods summary prior to taxi.There are a couple of key notes added into the software log stating that a ramp scanner deleted the Hazmat at close out.
