Age- and height-based prediction bias in spirometry reference equations.
Prediction bias in spirometry reference equations can arise from combining equations for different age groups, rounding age or height to integers or using self-reported height. To assess the bias arising from these sources, the fit of 13 prediction equations was tested against the Global Lungs Initiative (GLI) dataset using spirometric data from 55,136 healthy Caucasians (54% female). The effec...
متن کاملPrediction equations for spirometry in South Africa.
Prediction equations for spirometry in South Africa To the Editor: The South African Guideline for Office Spirometry was recently published. [1] Its aim was to provide an updated guideline for office spirometry in South Africa (SA), thereby improving the quality, standardisation and usefulness of spirometry. The need for local prediction equations based on large, allinclusive studies of the SA...
متن کاملSpirometry Reference Equations for Central European Populations from School Age to Old Age
BACKGROUND Spirometry reference values are important for the interpretation of spirometry results. Reference values should be updated regularly, derived from a population as similar to the population for which they are to be used and span across all ages. Such spirometry reference equations are currently lacking for central European populations. OBJECTIVE To develop spirometry reference equat...
متن کاملImplications of adopting the Global Lungs Initiative 2012 all-age reference equations for spirometry.
The aim of this study was to determine the diagnostic and interpretative consequences of adopting the Global Lungs Initiative (GLI) 2012 spirometric prediction equations. We assessed spirometric records from 17 572 subjects (49.5% females), aged 18-85 years, from hospitals in Australia and Poland. We calculated predicted forced expiratory volume in 1 s (FEV1), forced expiratory volume (FVC), FE...
متن کاملPrediction equations for spirometry in adults from northern India.
BACKGROUND Most of the Indian studies on prediction equations for spirometry in adults are several decades old and may have lost their utility as these were carried out with equipment and standardisation protocols that have since changed. Their validity is further questionable as the lung health of the population is likely to have changed over time. OBJECTIVE To develop prediction equations f...
