Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The following strategies will be used:
• Sealed Opaque Envelopes: Sealed envelopes containing allocation assignments will be used to maintain concealment until the point of enrollment.
• Pharmacy Dispensing: Partnership (My colleague Dr: Ali Al-fahd) will be made to dispense coded medications based on the participant's enrollment ID. The Partnership will maintain the allocation list and dispense the appropriate blinded medication without revealing the group assignment to the researcher.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (computerised sequence generation)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s

Intervention assignment
Parallel

Efficacy
Statistical methods / analysis
• Pain Scores (Continuous Data): Since pain scores are measured on a continuous scale (e.g., VAS), the following statistics will be conducted:
o Descriptive Statistics: Pain scores will be calculated for each group (calcium, ibuprofen, placebo) using measures like mean, standard deviation, and median. This will provide a basic understanding of how pain scores are distributed within each group.
o Analysis of Variance (ANOVA): This method will compare the mean pain scores between the three groups (calcium, ibuprofen, placebo) at each time point (baseline, post-procedure intervals). It will allow to assess whether there are statistically significant differences in pain levels among the groups.
o Post-hoc Tests: If ANOVA reveals significant differences, using post-hoc tests (e.g., Tukey's HSD) to identify which specific group pairs differ from each other in terms of pain scores.
• Onset and Duration of Pain Relief (Categorical Data):
o Chi-Square Test: This test will assess whether the distribution of these categories (onset or duration of pain relief) differs significantly between the groups.
Statistical Software:
• The data analysis will be performed using: SPSS V.25 (SPSS, JASP).
