1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

objectiveTo compare work of breathing (WOB) indices between two nCPAP settings and two levels of HFNC in a crossover study. STUDY

designInfants with a CGA 28-40 weeks, baseline of HFNC 3-5 lpm or nCPAP 5-6 cmH2O and fraction of inspired oxygen ≤40% were eligible. WOB was analyzed using respiratory inductive plethysmography (RIP) for each of the four modalities: HFNC 3 and 5 lpm, nCPAP 5 and 6 cmH2O. N=20; Study weight 1516 g (±40 g).

resultApproximately 12,000 breaths were analyzed indicating a high degree of asynchronous breathing and elevated WOB indices at all four levels of support. Phase angle values (means) (P<0.01): HFNC 3 lpm (114.7°), HFNC 5 lpm (96.7°), nCPAP 5 cmH2O (87.2°), nCPAP 6 cmH2O (80.5°). The mean phase relation of total breath (PhRTB) (means) (P<0.01): HFNC 3 lpm (63.2%), HFNC 5 lpm (55.3%), nCPAP 5 cmH2O (49.3%), nCPAP 6 cmH2O (48.0%). The relative labored breathing index (LBI) (means) (P≤0.001): HFNC 3 lpm (1.39), HFNC 5 lpm (1.31), nCPAP 5 cmH2O (1.29), nCPAP 6 cmH2O (1.26). Eighty-two percent of the study subjects-respiratory mode combinations displayed clustering, in which a proportion of breaths either occurred predominantly out-of-phase (relative asynchrony) or in-phase (relative synchrony).

conclusionIn this study, WOB indices were statistically different, yet clinically similar in that they were elevated with respect to normal values. These infants with mild-to-moderate respiratory insufficiency demonstrate a meaningful elevation in WOB indices and continue to require non-invasive respiratory support. Patient variability exists with regard to biphasic clustered breathing patterns and the level of supplemental fraction of inspired oxygen ≤40% alone does not provide guidance to the optimal matching of WOB indices and non-invasive respiratory support.
