"cohort level" is a correct and usable phrase in written English.
It is usually used to refer to a group of people studied or observed collectively as a unit. For example: "The researchers studied 17 different cohorts at the cohort level to analyze the impact of changing dietary behaviors."
Conclusions: In this small cohort, level of coma on admission was not predictive of recovery from a comatose state.
We also considered three-stage least squares estimates (with bootstrapped standard errors allowing for clustering at the birth cohort level) and they yield similar results.
Momentum, however, is a population level concept that does not provide a cohort level perspective or explicitly consider the descendants of a cohort.
We allow for clustering at the birth-year-community cohort level in the calculation of the standard errors to control for potential serial correlation among children born in the same community in the same year; this yields 64 clusters.19.19
The main outcomes assess clinically provided nutrition using STAR at the cohort level in an international context and then show a best nutrition rate is likely patient specific, particularly for patients requiring GC.
Standard errors calculated allowing for clustering at the birth-year-community cohort level (64 clusters) are shown in parentheses below coefficient estimates, which are in bold if significant at 5%% or lower; p values are in brackets.
At sub-cohort level, the age profile and occupational backgrounds of participants differed significantly.
At the inter-cohort level, there was a gradual but strong decline in the frequency of Pan IBB over the study period (= 199.3, P < 0.001) (Fig. 5).
To account for reductions in IPD incidence rates due to current PPSV use, we adjusted elderly minority IPD incidence rates at the age-cohort level using prior estimates of IPD incidence reductions due to PPSV [ 38].
Árnason et al. (2009) also detected distinct changes in Pan I genotype frequencies at the intra-cohort level, i.e. the Pan IBB genotype increased in frequency with age of the cod.
The authors estimated the fitness across age groups at the inter-cohort level and concluded that, in contrast to our study, the changes in the frequencies of the Pan IAA and Pan IBB genotypes were because of selection against the Pan IAA genotype (the coastal component) by high near-shore fishing pressure.
