We evaluated which equations best predicted the lung function of a cohort of nonagenarians based on which best accounted for subsequent survival. In 1998, we measured lung function, grip strength and dementia score (Mini Mental State Examination (MMSE)) in a population-based sample of 2262 Danes born in 1905. Mortality was registered to 2011 when only five (0.2%) subjects were alive. In half the cohort, we recorded forced expiratory volume in 1 s (FEV1). Complete data were available in 592… 
Applicability of the Global Lung Initiative 2012 Reference Values for Spirometry for Longitudinal Data of Elderly Women
TLDR
GLI z-scores fit cross-sectionally and longitudinally with FEV1, FVC and FEV 1/FVC measured in women from Germany which indicates that they can be used in longitudinal association analyses.
Airflow limitation by the Global Lungs Initiative equations in a cohort of very old adults
TLDR
In a cohort of very old adults, airflow limitation by GLI-LLN has lower prevalence than by fixed cut-off, independently predicts all- cause mortality and does not miss individuals with significantly higher all-cause mortality and hospitalisation.
Impaired lung function and mortality in Eastern Europe: results from multi-centre cohort study
TLDR
Reduced FEV1 is an independent predictor of all-cause mortality, with risk increasing with the degree of lung function impairment and some country-specific variation between the cohorts.
All-cause and cardiovascular mortality in relation to lung function in the full range of distribution across four Eastern European cohorts
TLDR
FEV1/height3 is a strong predictor of all-cause and cardiovascular mortality, across full distribution of values, including persons with preserved lung function, with some statistically insignificant variation.
Reference Equations for Spirometry in the Canadian Population.
TLDR
This study provides spirometric reference equations for the Canadian population that were measured under the recommended clinical conditions and with rigorous quality control.
Comparison of NHANES III and ERS/GLI 12 for airway obstruction classification and severity
TLDR
There are significant differences when using GLI 12 and NHANES III to diagnose airway obstruction and severity in Caucasian patients aged 18–95 years, and similarities and differences exist between NHANes III andGLI 12 for some age and height combinations.
Avoiding ageism and promoting independence from reference equations in lung function testing of older adults
TLDR
Spirometry quality and interpretation in very old adults needs to be further researched, especially the use of FEV1 expressions that are independent of reference equations/values.
Choosing and using lung function prediction equations

  • 2016
TLDR
Two groups of European researchers have looked at their local populations to see if the GLI-2012 equations were a satisfactory fit and so can be safely used for clinical decision making.
Prediction of 30-day mortality for acute chronic obstructive pulmonary disease exacerbation in the emergency room
TLDR
Age, SBP, CAR, procalcitonin, HICU, and FVC are predictors for 30-day mortality in patients who admit to ER with AECOPD.

Validation of lung function prediction equations from patient survival data
TLDR
Using patient survival data is a new approach to help select which lung function prediction equations to use, concluding that LMS or Miller spirometry equations and Miller’s DL,CO equations were best for the patient population.
Predictors of loss of lung function in the elderly: the Cardiovascular Health Study.
TLDR
The most notable finding of these analyses was that current smoking was associated with more rapid rates of decline in FVC and FEV1, and African-Americans (especially women) had slower rates of collapse than did whites.
Pulmonary function is a long-term predictor of mortality in the general population: 29-year follow-up of the Buffalo Health Study.
TLDR
It is suggested that pulmonary function is a long-term predictor for overall survival rates in both genders and could be used as a tool in general health assessment.
Which spirometric indices best predict subsequent death from chronic obstructive pulmonary disease?
TLDR
This study confirms FEV1 and mid expiratory flow rates as powerful predictors of mortality from COPD, and suggests that measurement of end expiratories flow rates would add little extra predictive information.
Estimation of ventilatory capacity in subjects with unacceptable lung function tests.
TLDR
The findings suggest that alternative strategies for handling non-reproducible lung function may need to be explored in order to avoid selection bias and that test failures should be excluded from the analysis of epidemiological data.
Precision in Diagnosing and Classifying COPD: Comparison of Historical Height with Current Height and Arm Span to Predict FEV1
TLDR
The study suggests that current measured height, derived from armspan, may give a more accurate measure of ‘normal’ lung volumes and hence the degree of impairment of FEV1 and hence progression of COPD.
Multi-ethnic reference values for spirometry for the 3–95-yr age range: the global lung function 2012 equations
TLDR
Spirometric prediction equations for the 3–95-age range are now available that include appropriate age-dependent lower limits of normal for spirometric indices, which can be applied globally to different ethnic groups.
Respiratory muscle strength and the risk of incident cardiovascular events
TLDR
A reduced MIP is an independent risk factor for MI and CVD death, and a suggestion of an increased risk for stroke, and this association appeared to be mediated through mechanisms other than inflammation.
Spirometric reference equations for European females and males aged 65–85 yrs
