title: The association between Erection Hardness Grading Scale and International Index of Erectile Function in men with erectile dysfunction treated with sildenafil citrate.
abstract: BACKGROUND
  To evaluate the association between the first 5-item version of the International Index of Erectile Function (IIEF-5) and Erection Hardness Grading Scale (EHGS) scores in patients who received sildenafil citrate treatment due to erectile dysfunction (ED).
  
  
  METHODS
  A total of 81 men with ED lasting for 6 months or longer were included in this study. Mean age was 51 years (range 21-75). All patients were given 50 mg sildenafil citrate (Viagra®) 4 times a week during an 8-week period and they were asked to attempt sexual intercourse when they used the drug.
  
  
  RESULTS
  The mean pretreatment IIEF-5 and EHGS scores were 6.7 ± 2.5 and 1.7 ± 0.5, respectively. These values were 15.3 ± 5.1 and 2.8 ± 0.6 after the treatment, respectively. There were statistically significant differences in all scores between before and after treatment for IIEF-5 and EHGS scores (p < 0.001). We found a very strong association between IIEF-5 and EHGS scores in the pretreatment period (gamma = 0.916, p < 0.001). However, there was a fair agreement between IIEF-5 and EHGS scores (kappa coefficient: 0.375).
  
  
  CONCLUSIONS
  Our experience showed that there was no significant agreement between the IIEF-5 and EHGS scores in patients treated with sildenafil citrate.
