2. need for antibiotics prescription up to 7 days post treatment
Patient will receive a phone call. in addition the health system in out hospital is connected we plan to check the patient file if he visited the emergency room and antibiotics is prescribed or not.
Timepoint [2] 346736 0
patient will be called at 7 days post treatment to check if they started antibiotics through out the week after treatment.
Secondary outcome [3] 346737 0
3. side effect of the studied mediation
this is self reported. patients will be asked about new symptoms started post treatment.
up to seven days.
Studies found that most of the symptoms noticed after the treatment are more related to the disease and are not real side effect of the medication.
the following side effects may be experienced:
1. nausea
2, vomiting
3. myalgia
4. hiccups
5. headache
Timepoint [3] 346737 0
patient will be called at one week post treatment to ask about any self reported side effects

Power Analysis
After a follow-up of at least 24 hours, 74 patients will be needed (37 on each group) to have 90% power to detect an average mean difference of pain score of 2.1 from visual analogue scale between the two treatment arms (4.5 to 2.4) at the 5% alpha (significance) level. Because of missing data and losses to follow-up, an additional 26 subjects will be needed (50 in each arm) for a total of 100 subjects (study sample).

Statistical Analysis
Descriptive statistics will be used to describe the data. For categorical variables, frequencies and percentages will be reported. Differences between groups will be analyzed using Pearson’s ( statistical test applied to sets of categorical data to evaluate how likely it is that any observed difference between the sets arose by chance.) tests. For continuous variables, mean and standard deviation will be used to present the data while analysis will be performed using Student’s t-tests. For non-normal distributed continuous variables, median and interquartile range (IQR) will be used to summarize the data and analysis performed using Wilcoxon-Mann-Whitney tests. An a priori two-tailed level of significance will be set at <0.05 level. Statistical analyses will be conducted using STATA version 13.1 (STATA Corporation, College Station, TX, USA).

Summary
Brief summary
We aim to conduct a prospective randomized single blinded trail in the family medicine clinic and student clinic in the Sultan Qaboos University Hospital to assess the effectiveness of steroid in the management of sore throat. All adult patients aged more than 18 years old present with sore throat will be invited to take part in the study. The primary end point of evaluation is a change in the patient subjective rating of her or his pain. Patients who will be included will be randomized to either arms of the stuy. Each participant will be given an envelope which has either dexamethasone 10 mg (5 tablets, each of 2 mg) and the symptomatic treatment) ---or---- symptomatic treatment only together with the visual analogue score. Both treatment arms will be given the symptomatic treatment. The symptomatic treatment which is planned to be given includes antihistamin and antipyretic which are the usual treatment of sore throat. Patients will be asked to rate their pain on a visual analogue scale (VAS) from 0 to 10, with 0 being no pain and 10 being the worst pain imaginable. On enrolment, demographics, presenting symptoms and the VAS score for pain will be collected. Telephone follow-up will be performed as close to 12 hours and 24 hours and 48 hours after treatment as possible. During each telephone follow-up, patients will be asked to rate their current pain by using the VAS and to provide the time of initial onset of pain relief and the time of complete resolution of pain. The study will look at the following secondary outcome: time to complete symptoms resolution (VAS equal to zero), need for antibiotics prescription up to 7 days post treatment and self-reported side effects.



The study has two arms. Both arms will receive the usual symptomatic treatment which include antihistamine and antipyretic. The intervention group will be given dexamethasone in addition to the usual symptomatic treatment, The control group will not be given it. Both groups will have the same follow up plan.
