Recruitment was terminated with achievement of the sample size.
Participants are recruited from lung cancer clinics at 4 Sydney hospitals, commencing May 2009 until achievement of planned sample size.
Twelve studies reported a power calculation (21, 22, 24– 33, 34, 34), with nine reporting achievement of required sample sizes at final follow-up (21, 22, 26– 34, 34).
This approach was used to ensure achievement of NHIF sample size since there are relatively fewer NHIF members at the ward or village level.
Table 2 presents an overview of the samples in the respective countries and studies in terms of age, grade, and the test months, along with information on the average reading achievement of the samples.
The size of the adenopathy and the presence of indirect signs at the puncture site predict the achievement of diagnostic samples.
In systematic sampling, the first patient was randomly selected and the others were drawn from the clinic database according to a sample interval defined as N/n until achievement of the desired sample size.
Credibility was enhanced through prolonged engagement with participants, the achievement of saturation, sampling approach (maximum variant sampling).
In consecutive sampling, the first patient was randomly selected, then patients consecutively registered were selected until the achievement of the required sample size.
After two months of recruitment, the upper age limit was raised to 35 years old, and this resulted in achievement of the required sample size.
