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
Objective: The aim of this paper is to compare the results of uing two methods designed to objectify nasal patency in patients with external and internal nasal valve obstruction. Methods: Nasal flow was measured by a flowmeter (behind the nasal valve area) and peak nasal inspiratory flow (PNIF; in front of the nasal valve area) separately for each side of the nasal cavity. Results: Data included information from a total of 38 sides of the nasal cavity - 19 sides of the nasal cavity with an obstruction in the area of the nasal valve and 19 sides of the nasal cavity without an obstruction. There were no statistically significant differences in terms of age (p = 0.299), gender (p = 1.000) and flowmetry values (4.28 Conclusions: To determine the contribution of obstruction to the clinical condition in the nasal valve area, it is appropriate to use a combination of methods measuring in the area in front of and behind the nasal valve. According to our observations, the combination of PNIF and flowmetry may be advantageous in the evaluation of these patients.
