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
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.
