Description of intervention(s) / exposure
341 people (from a private practice clinic) with diagnosed autoimmune inflammatory disease that have had mannose binding lectin levels recorded will be posted a questionnaire to determine the number and frequency of infection over the past 7 years. Those who fail to return the questionnaire will receive a follow up phone call 4 weeks later.

Outcomes
Primary outcome [1] 298019 0
Level of mannose binding lectin was measured using the MBL Oligomer ELISA kit to determine the concentration in human serum.
Timepoint [1] 298019 0
Baseline
Primary outcome [2] 298020 0
Number of urinary tract infections verified by urine sample and laboratory testing as recorded in patient notes.
Timepoint [2] 298020 0
Completed at single timepoint in relation to previous 7 years
Secondary outcome [1] 322911 0
Details concerning the number of infections were obtained by conducting a retrospective audit of hospital admission records and a state-wide government Health database, for all participants. That an infection had occurred, it’s nature and the outcome of treatment was recorded.
Timepoint [1] 322911 0
Completed at single timepoint in relation to previous 7 years

Statistical methods / analysis
This is an explorative study. We have 341 case records of females with autoimmune conditions. We will examine these to determine if there is a relationship between urinary tract infections and mannose binding lectin deficiencies. Since there is little published data on this relationship, we are unable to perform a power calculation based on prior research findings.
Descriptive statistics will be presented as means and standard deviations for continuous variables and as percentages for categorical variables. Statistical analysis will be carried out using simple parametric tests as well as Poisson regression models (to investigate factors related to the incidence of Serious Infections) and Logistic regression models (to investigate factors related to multiple serious infections). Rate ratios and 95% confidence intervals will be reported.
t tests - Correlation: Point biserial model

Analysis: Post hoc: Compute achieved power
Input: Tail(s) = Two
Effect size |p| = 0.3

Output: Noncentrality parameter d = 5.8073466
Critical t = 1.9669865
Df = 339
Power (1-beta err prob) = 0.9999362
