We aimed to investigate how celestial phenomena like zodiac signs, lunar phases, and Friday the 13th impacted the risk of reoperation after groin hernia repair.
We conducted a nationwide register-based study based on the Danish Hernia Database and Danish Patient Safety Authority's Online Register between 2000-2019. We included patients ≥18 years undergoing open Lichtenstein or laparoscopic groin hernia repair. The main outcomes were risk of reoperation after groin hernia repair in relation to patient and surgeon zodiac sign, lunar phase at the time of the repair, and Friday the 13th vs other Fridays.
151,901 groin hernias were included in the analysis of patient zodiac sign, and 25,075 groin hernias were included in the analysis of surgeon zodiac sign. Compared with the Sagittarius, there was a significantly higher risk of reoperation (HR [95% CI]) if the performing surgeon was born under the Capricorn (1.93 [1.16-3.12]); Pisces (1.68 [1.09-2.57]); Aries (1.61 [1.07-2.38]); Taurus (1.62 [1.04-2.54]); Cancer (2.21 [1.48-3.28]); or Virgo (1.71 [1.13-2.59]). Repairs performed under the waxing (1.23 [1.03-1.46]) and the new moon (1.54 [1.11-2.13]) had significantly higher risk of reoperation (HR [95% CI]) compared with the waning moon. Neither patient zodiac sign nor Friday the 13th affected risk of reoperation after groin hernia repair.
Surgeons' zodiac sign and lunar phase significantly affected the risk of reoperation after groin hernia repair. Neither patients' zodiac sign nor Friday the 13th influenced on the risk of reoperation after groin hernia repair. This indicates why significant findings should be considered carefully to distinguish between random statistical association and cause-and-effect relations.
我们旨在研究诸如星座、月相和13号星期五等天文现象如何影响腹股沟疝修补术后再次手术的风险。
我们基于丹麦疝数据库和丹麦患者安全管理局的在线登记系统，在2000年至2019年期间开展了一项全国性的基于登记的研究。我们纳入了年龄≥18岁且接受开放式Lichtenstein手术或腹腔镜腹股沟疝修补术的患者。主要结局是腹股沟疝修补术后再次手术的风险，该风险与患者和外科医生的星座、修补时的月相以及13号星期五与其他星期五的情况有关。
151,901例腹股沟疝纳入了患者星座分析，25,075例腹股沟疝纳入了外科医生星座分析。与射手座相比，如果主刀医生是摩羯座（风险比[95%置信区间]为1.93[1.16 - 3.12]）、双鱼座（1.68[1.09 - 2.57]）、白羊座（1.61[1.07 - 2.38]）、金牛座（1.62[1.04 - 2.54]）、巨蟹座（2.21[1.48 - 3.28]）或处女座（1.71[1.13 - 2.59]），再次手术的风险显著更高。与残月相比，在月盈（风险比[95%置信区间]为1.23[1.03 - 1.6]）和新月（1.54[1.11 - 2.13]）时进行的修补再次手术风险显著更高。患者星座和13号星期五均未影响腹股沟疝修补术后再次手术的风险。
外科医生的星座和月相对腹股沟疝修补术后再次手术的风险有显著影响。患者星座和13号星期五均未影响腹股沟疝修补术后再次手术的风险。这表明为何应谨慎考虑显著发现，以区分随机统计关联和因果关系。
