Was the assignment of patients totreatments randomised?
This was investigator blind,randomized, parallel group, multiplearm comparative , single dose trialcarried out at Pediatrics department of atertiary care teaching hospital.
Yes, randomized
Based on computer generatedrandomization , block randomizationwas used to assign three sequences to33 subjects in each group in the ratio of1:1:1.

Aside from the allocated treatment, weregroups treated equally?
For ibuprofen 10 mg/kg or paracetamol 15mg/kg or both ibuprofen and paracetamol,with the help of calibrated measuring cylinderwith 60 ml of water.Primary study objective was the reduction inthe tympanic temperature from the baselinetemperature at the end of 4 h after drugadministration.
Afebrile children at 1, 2, 3 and 4 h post dose,
any adverse drug events occurring during the4 h period were recorded.
Yes, differrent groups were treatedequally.

Were measures objective or were the patients andclinicians kept blind to which treatment was beingreceived?
This was investigator blind.Participants were allocated by theunblinded investigator to one of thethree treatment arms.
Double blind design would have beenideal but would have been complicatedand not likely to be acceptable byparticipants hence investigator blinddesign was considered.

How large was the treatmenteffect?
There was a significant difference between threegroups ( P = 0.013 ), maximum reduction intemperature in combination group andminimum in paracetamol group .

Post-hoc multiple comparisontest between the three groups
Untuk menghitung relative risk Antara PCT-Ibuprofen, PCT-Kombinasi, Ibuprofen-Kombinasi

Between paracetamol andcombination group ( P = 0.03)
Pasien menjadi afebris setelah 4 jam RR = T/K = 0.93/ 0.76 = 1.22
Since the RR > 1, the treatment increases the
afebrile patients. ARR = K-T = -0.17
The absolute benefit of treatment is a 17%increase in afebrile patients.
RRR = 1-RR = -0.22The treatment increase the afebrile patient by22% relative to that occurring in thePCT/control group.
NNT = 1/ARR = -5.88

How precise was the estimateof the treatment effect?
In this study, the difference intemperature reduction between twogroups (PCT & Combination) although
statistically significant ( P = 0.013 ), wasnot clinically significant less than 1C(0.71C).

Will the results help me incaring for my patient?
Is my patient so different to those inthe study that the results cannotapply? No, it isnt This study population is Indian children
Is the treatment feasible in my setting? Yes, it is Walaupun sediaan kombinasi PCT-

Will the potential benefits of treatment
outweigh the potential harms oftreatment for my patient? Yes, it will If quicker reduction in body temperature is
the goal of therapy.
Both antipyretics have been found to beequally safe in children.[9]
PCT should be used preferentially due to alower risk of adverse effects.[6,10]
Ibuprofen has the advantage of less frequentdose (every 6-8 h vs. every 4 h for PCT).[11]
