effect

“To sum up, causes and EFFECTS are not real (or at least not knowable), but imagined by our mind to make sense of the observation that ‘A’ often occurs together with, or slightly before ‘B’. All we can observe are correlations, not causations.”
An effect is also the power to bring about a result, working as an influence:

“While the end RESULT (i.e. a cost reduction) appears to be the same, the process used to achieve that RESULT can have longer-term implications. Cooperation may reduce costs through joint improvement while heavy-handed cost pressure might force a supplier to cut corners, resulting in poor quality.”
influence
Whereas impact is of a single event, influence is extended over a period of time (reflecting the etymology of influence in emanation from the stars that acts upon one’s character and destiny, and a flow of water, a flowing in). Also the power to have an effect on people or things.

consequence

Asserting the relation of a result or effect to its cause or antecedent:

upshot
Originally, the final shot in an archery match, hence the figurative sense of end result or outcome:
