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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Measuring maximal airway pressure is an essential part of the assessment of respiratory functions. Portable handheld devices have made clinical measurements more available, but reliable and user-friendly devices for non-clinical use remain rare. This study sought to determine the validity and short-term repeatability of measurements of dynamic maximal inspiratory pressure (dMIP) and dynamic maximal expiratory pressure (dMEP) by using a novel self-administered respiratory health meter (WellO2-RHM) in asymptomatic young adults. Patients and Methods: dMIP and dMEP were measured with WellO2-RHM in asymptomatic adult volunteers (n=26, 15 male and 11 female, age 26-41 years). These values were compared with quasi-static maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) obtained from the same volunteers using another respiratory manometer (MicroRPM). The measurements of dMIP and dMEP with WellO2-RHM were repeated in the same individuals at an interval of one week for assessment of their short-term repeatability. Results: The Pearson correlation coefficients of dMIP and dMEP values with MIP and MEP values were high (r=0.840, p<0.001; r=0.849, p<0.001, respectively). The dMIP and dMEP values were consistently lower than the quasi-static MIP and MEP values in the same individuals. The short-term repeatability of the dMIP and dMEP in one week interval proved to be moderately good in terms of the coefficient of variation (CV), the intraclass correlation coefficient (ICC), the standard error of measurement (SEm) and minimal detectable change (MDC) (10.0%, 0.825, p<0.001, 7 cmH2O and 20 cmH2O and 9.1%, 0.895, p<0.001, 12 cmH2O and 34 cmH2O, respectively). Conclusion: The results indicate that the WellO2-RHM is a valid and repeatable method for the assessment of dMIP and dMEP in asymptomatic young adults, but the absolute values are lower than those obtained with devices measuring quasi-static MIP and MEP. The findings suggest that WellO2-RHM can be used for self-monitoring of the effects of respiratory muscle training in healthy young adults.
