TPE, tuberculous pleural effusion; TB, tuberculosis; B, coefficient for the constant; s.e., standard error; Wald, Wald χ2 value; df, degrees of freedom; Sig., significance probability or p value; Exp (B), exponentiation of the B coefficient.
Variables entered in the logistic regression model: smoking, regular alcohol use, history of contact with TB patient, past history of TB, family history of TB and underweight; ‘Smoking’ as a variable includes either beedi or cigarette smoking.
