Consider you have a shot that prevents miscarriages. If 10 people took the shot at 1 had a miscarriage, then they made the shot even more effective and 1000 people took it and 3 had a miscarriage, a headline of “miscarriages increase 200% under new modified shot” would be factually correct, even though the shot is now 3,333% more effective. (Note: still suffering from low sample size but I am just giving an example of how to mislead w statistics)
