A study in UK of 5174 bihs at home and 11156 bihs in hospitals showed perinatal moality rates of 5.4/1000 in home bihs and 27.8/1000 in the hospital bihs. This observed association between perinatal moality and hospital bihs is called as
High-Yield Explanation
In the given question, perinatal moality rate is more in hospital bihs than in home bihs, which is practically unreal; hence it is Spurious association. Mostly complicated cases with high risk of moality reach hospitals. Hence higher morltaltiy is observed. Spurious association - Observed association between disease and suspected factor may not be real.
