*SSB – small scale business ** significant factors associated with splenomegaly.

R² = 0.0564, Adjusted R² = 0.0445 F = 4.72 and P< 0.0001.

Linear regression model was constructed for height adjusted ultrasound measurements of the spleen (organ size as continuous variable-i.e. deviations from mean).
