Study designs were divided into the following categories: (1) prospective studies of dengue cases, (2) studies analyzing post-hoc existing prospectively collected databases of dengue cases, (3) studies reviewing retrospectively existing medical charts of dengue cases, and (4) acceptability studies (mostly of qualitative design).
The charts of discrepant cases were reviewed in detail in order to identify possible reasons for discordance.
Patient charts of five cases of microsporidial stromal keratitis diagnosed between January 2002 and June 2004 were reviewed retrospectively for clinical data, microbiologic and histopathologic data.
For verification of the questionnaires, we reviewed the medical charts of all cases, as well as reports on endoscopy, surgery and pathology.
Medical charts for cases of RMSF diagnosed between June 1 , 2002and September 30, 2011 from Indian Health Service (IHS) facilities and referral hospitals were reviewed by Regan and others 4 and Traeger and others.
In addition, personal contact as well as telephone interview and/or review of medical charts in case of re-admission of patients served for data acquisition.
Study Design: We performed a retrospective chart review of cases of uterine rupture from 1976 to 1998.
A retrospective chart review of cases between 2010 and 2017 at a tertiary uveitis referral center in the United States of America was conducted.
Chart review of cases also documented information on additional malformations so that MSAFP analyses on the subgroups of both isolated and complex fetal hydrocephalus could be performed.
In our initial investigation, chart review of cases with International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes of 729.4 (fasciitis), 728.86 (necrotizing fasciitis), and 608.83 (Fournier's gangrene) were also carried out.
