Abstract

Background: PEAK nasal inspiratory flow (PNIF) has been proposed as a simple method to evaluate nasal patency. Asthma and allergic rhinitis are commonly associated, and lower airway assessment can provide information concerning an objective interpretation of nasal function. Aims: TO determine whether the PNIF is correlated with peak expiratory flow (PEF) in children and adolescents. Methods and results: Cross-sectional study carried out in healthy students randomly chosen in 14 public schools of the city of Belo Horizonte. PNIF and PEF were assessed for each subject as the following characteristics: gender, height, weight and age. We created a linear regression model to explain the PNIF, in which we included all the variables with a p value ≤ 0.25 in a univariate analysis, and to calculate the relationship between the maximum PNIF and maximum PEF by the Spearman correlation coefficient. In total, 297 healthy subjects, aged between six and eighteen years were evaluated. A positive and significant correlation between PNIF and PEF was found. Conclusions: PEF is predictive of PNIF. However, these measures evaluate two distinct segments of the airways and should be both obtained for a more precise assessment of airflow limitation.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A low PNIF quotient could correspond to an increase in bronchial resistance rather than a decrease in PNIF.

    “since a low quotient could correspond to an increase in bronchial resistance rather than a decrease in the PNIF.”

    From Position Paper on Nasal Obstruction: Evaluation and Treatment (2018) · cites this paper as [58]

    The Discussion (page unavailable) says low PNIF values may reflect reduced lower-airway patency and should be checked against PEF. That supports the concern about a bronchial contribution, but the paper does not discuss a low PNIF quotient or establish that increased bronchial resistance, rather than decreased PNIF, explains one. (LLM, conf=0.82)

    Experimental — accuracy not yet measured

  • PNIF is closely related to maximum expiratory flow.

    “PNIF is closely related to maximum expiratory flow [58,63,66,67]”

    From Position Paper on Nasal Obstruction: Evaluation and Treatment (2018) · cites this paper as [58]

    The Discussion reports a positive, statistically significant correlation between PNIF and peak expiratory flow in 297 healthy children and adolescents, but describes it as moderate (r = 0.433; p ≤ 0.001). “Closely related” overstates the reported strength, and the unqualified claim extends beyond the population studied. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • A wide range of values of normality for PNIF have been published in adults and children.

    “A wide range of values of normality have been published in adults [31,44,58-61] and children [58-61].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
