  • Data are means (SEs) or estimated coefficients (SEs). Preferred case management is defined as the use of an inhaler or bronchodilator for the asthma case, ORS for the child diarrhoea case, a sputum test for the tuberculosis suspect, and a referral, ECG or aspirin for the unstable angina case. Control indicator variables are included for each case. Price includes all testing and medications recommended by the provider.

  • Asterisks indicate significance levels as follows: ***p<0.01, **p<0.05, *p<0.1.

  • ORS, oral rehydration salts.
