Our results indicate that RV size may be more difficult to evaluate, especially when the dilatation RV is moderate, requiring the longer training program.
The severity of injury was determined using the WHO Injury Surveillance Guideline coding recommendations: (1) no apparent injury; (2) minor or superficial injury; (3) moderate, requiring some skilled treatment (e.g., sutures); (4) severe, requiring intensive medical/surgical management [8].
Moderate: requiring treatment or prolonging stay in hospital.
AE were graded as follows: 1 - mild, not requiring intervention; 2 - moderate, requiring minimal local or noninvasive intervention; 3 - severe, 4 - life-threatening; 5 - death.
Bleeding was described as major (life-threatening, compromising haemodynamic status or requiring urgent intervention), moderate (requiring non-urgent transfusions) or minor (all other events).
Adverse events related to surgery were predefined and graded as mild (requiring no treatment), moderate (requiring treatment), or severe complications (requiring surgical intervention, ie, wound exploration for active bleeding, repair of wound dehiscence, hospitalization, or referral for specialized care).
severe: fatal or potentially life threatening or causing permanent disability; moderate: requiring treatment or prolonging stay in hospital or causing interference with normal daily activities; mild: minor reactions that do not require treatment and do not prolong stay in hospital.
Their severity was classified as mild (self-managed change in treatment), moderate (requiring a visit to a physician), severe (hospitalisation in a medical ward) or very severe (hospitalisation in an intensive care unit).
Meconium aspiration syndrome is defined as respiratory distress in the first four hours after birth in presence of meconium stained amniotic fluid and categorised as severe (requiring assisted mechanical ventilation) or moderate (requiring oxygen for at least 48 hours or at a concentration of 40percentt or greater but without mechanical ventilation).
An exacerbation was defined as an increase in dyspnea, sputum purulence, and increased sputum volume and classified as moderate (requiring a visit to a doctor or the emergency department and treatment with antibiotics or systemic steroids or both) or severe type II (requiring hospital admission) [ 22].
