_D_e_s_c_r_i_p_t_i_o_n:

     Data from an observational study of 996 patients receiving a PCI
     at Ohio Heart Health in 1997 and followed for at least 6 months by
     the staff of the Lindner Center. This is a landmark dataset in the
     literature on propensity score adjustment for treatment selection
     bias due to practice of evidence based medicine; patients
     receiving abciximab tended to be more severely diseased than those
     who did not receive a IIb/IIIa cascade blocker.

_U_s_a_g_e:

     data(lindner)

_F_o_r_m_a_t:

     A data frame of 10 variables collected on 996 patients; no NAs.

     _l_i_f_e_p_r_e_s Mean life years preserved due to survival for at least 6
          months following PCI; numeric value of either 11.4 or 0.

     _c_a_r_d_b_i_l_l Cardiac related costs incurred within 6 months of
          patient's initial PCI; numeric value in 1998 dollars; costs
          were truncated by death for the 26 patients with lifepres ==
          0.

     _a_b_c_i_x Numeric treatment selection indicator; 0 implies usual PCI
          care alone; 1 implies usual PCI care deliberately augmented
          by either planned or rescue treatment with abciximab.

     _s_t_e_n_t Coronary stent deployment; numeric, with 1 meaning YES and 0
          meaning NO.

     _h_e_i_g_h_t Height in centimeters; numeric integer from 108 to 196.

     _f_e_m_a_l_e Female gender; numeric, with 1 meaning YES and 0 meaning
          NO.

     _d_i_a_b_e_t_i_c Diabetes mellitus diagnosis; numeric, with 1 meaning YES
          and 0 meaning NO.

     _a_c_u_t_e_m_i Acute myocardial infarction within the previous 7 days;
          numeric, with 1 meaning YES and 0 meaning NO.

     _e_j_e_c_f_r_a_c Left ejection fraction; numeric value from 0 percent to
          90 percent.

     _v_e_s_1_p_r_o_c Number of vessels involved in the patient's initial PCI
          procedure; numeric integer from 0 to 5.
