From censoring cases who died from non-pneumonia causes and adjusting for age, monthly income, and the CCI score, we found that PC patients who received treatment with GnRH agonists were more likely to be hospitalized for treatment of pneumonia during the 1-year follow-up period than PC patients who did not receive treatment with GnRH agonists. Here, GNRH1 is linked to susceptibility to pneumonia measurement.
