Table 2 Impact of lunar cycle on intra-and postoperative morbidity, mortality and long-term survival

From: The dark side of the moon: Impact of moon phases on long-term survival, mortality and morbidity of surgery for lung cancer

outcome parameter test used   independent factor  
   day of lunar cycle vs. each other 4 moon phases vs. each other waxing vs. waning moon full moon vs. remaining phases
Survival log-rank P = .459 P = .646 P = .631 P = .110
operative complications χ 2 P = .963 P = .430 P = .579 P = .941
post-OP mortality χ 2 P = .885 P = .952 P = .756 P = .920
post-OP morbidity χ 2 P = .846 P = .910 P = .967 P = .970
  1. Outcome parameters are not significantly affected by moon phase.
