The presence of H. pylori in stomach tissues was identified by visualization of spiral microorganisms in histology sections and/or by immunohistochemistry. Four-micron tissue sections were de-waxed in xylene and decreasing grades of ethanol.
For the tissue sections, we followed the same procedure as mentioned previously after removing paraffin using xylene and hydrating the section using decreasing grades of alcohol (100%to20%0%).
Four-micron sections of formalin-fixed, paraffin-embedded (FFPE) tissues were deparaffinised in xylene for 5 minutes and gradually rehydrated in decreasing grades (100%, 90 %, 80 % and 70 of industrial methylated spirits (IMS) and water washes.
The alcohol-fixed smears were hydrated through decreasing grades of alcohol, washed in phosphate buffered saline (PBS) for 10 min, and treated with 3%H2O22 for 15 minutes and then incubated with in-house absorbed polyclonal anti-MPT64 antibody (received from the University of Bergen, Norway) at 1/250 dilution.
The overall objectives of the CPS are stated as improving Grade 1 school performance and age 6 enrolments and decreasing Grade 1 drop-out rates.
For immunohistochemistry, the sections were treated with xylene and rehydrated with decreasing graded ethanol washes.
Sections were deparaffinised in xylene and re-hydrated through decreasing graded alcohols.
In addition, the Flesch Reading Ease and Flesch-Kincaid Grade Level metrics were utilized to modify item language, thereby increasing reading ease, decreasing grade level, and allowing items to be more easily understood by patients and parents.

Furthermore, the vast majority of assessments demonstrated increased grades, rather than unchanged or decreased grades.
