To determine the types and frequency of ocular conditions that simulate retinoblastoma (pseudoretinoblastoma) based on age at presentation.
Subsamples were established by trifurcating the sample based on age at the time of the boys' first documented PSB, resulting in age cohorts reflecting early childhood (age two to seven), middle childhood (age eight to 11), and preadolescence/adolescence (age 12 17).
To test the sensitivities of recently published American recommendations predicting occult intracranial lesion (OICL) in girls with central precocious puberty (CPP), and to validate a previously derived diagnosis rule predicting OICL based on age at puberty onset and estradiol (E2) level.
Patients were divided into 3 groups based on age at the time of surgery (<55, 55-70, and >70 years).
Subjects were further stratified into five groups based on age at initial ablation: group 1, age < 35 years; group 2, age 35 39 years; group 3, age 40 44 years; group 4, age 45 49 years; and group 5, age ≥ 50 years (Fig. 2).
Three types of Gaucher disease are clinically delineated, based on age at recognition and organ involvement.
[39] Patients with CD were assessed according to the Montreal classification [40] based on age at diagnosis (A), location (L), and behaviour (B) of disease.
Patients with CD were assessed according to the Montreal classification [33] based on age at diagnosis (A), location (L), and behaviour (B) of disease.
Note that the data used to obtain the corresponding cumulative risk of death of mutation carriers Fbo(x) above is based on age at diagnosis which is necessarily earlier than the expected age at death.
We fit a multivariate logistic regression model for predicting positive TST based on age at entry, time spent in health care after entry, sex, BCG scar and contact with TB patients.
Data from study participants were analyzed in stratum based on age at initial enrollment (7).
