Criteria for considering studies for this review
There were no restrictions on the article’s publication date. We evaluated all case reports, case series and observational studies that were about the prevalence of PCP in patients with AML. Studies with relevant information were included in the final analysis. Titles, abstracts, and full texts of the recorded studies were evaluated based on the inclusion and exclusion criteria. The inclusion criteria were as follows: 1) studies including clinical trials, observational studies, case reports, case series and case letters on PCP and AML. We select papers with no date restriction which evaluated incidence of PCP in AML patients, clinical manifestations, chemotherapy regimen, phase of treatment and also outcome; 2) availability to the full-text articles; 3) only English language articles. Studies with at least one of the following aspects were excluded: 1) studies with non-relevant information, 2) studies with language other than English, 3) review articles and letters, 4) duplicate studies and 5) articles available only in abstract form. Appropriate papers were selected after evaluating all studies based on the inclusion and exclusion criteria.
