For sample adults in 2002 who had used chelation for their own health during the past 12 months (CHEYR) and had used chelation to treat at least one specific health problem or condition (CHETREAT), CHECON1HELP reports the degree of help that the respondent received from using chelation to treat the first of the three conditions considered most bothersome (CHECON1).

The 2002 NHIS recognized 74 conditions (including an "other" category) that respondents could have treated with chelation. (See CHETREAT for the full list.) To obtain responses to CHECON1, CHECON2, and CHECON3, the interviewer first asked, "For what health problems or conditions did you use chelation?" After recording all answers, the interviewer displayed the list of conditions reported by the respondent and asked, "Which three of these are the most bothersome?"

Respondents were then asked, "How much do you think chelation helped your (display for each condition)? Would you say a great deal, some, only a little, or not at all?" Responses to this question are reported in CHECON1HELP, CHECON2HELP, and CHECON3HELP.
