Safety measurements
Safety assessments were based on reports of adverse events
(AEs) and results of routine physical examinations, laboratory determinations
and vital sign measurements. . All of the AEs were
monitored throughout the study and assessed to see if there was a
direct relationship between this intervention and that specific
complication that they had reported. Patients with clinically relevant
AEs and/or abnormal laboratory test results at the final visit
were questioned about whether the condition existed before the
start of the study or it had increased in severity or frequency during
the study. Quince syrup was well tolerated by most of the patients,
and no adverse effects, neither local nor systemic, were reported by
them. Moreover, no abnormal physical examination was noted on
the follow-up contacts.
