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
Distortion products are tones produced through nonlinear effects of a system simultaneously detecting two or more frequencies. These combination tones are ubiquitous to vertebrate auditory systems and are generally regarded as byproducts of nonlinear signal amplification. It has previously been shown that several species of infectious-disease-carrying mosquitoes utilize these distortion products for detecting and locating potential mates. Furthermore, the mechanical tuning curve of the male mosquito flagellum was shown not to be aligned with that of its sensory neural elements. Using a generic theoretical model for acoustic sensing, we evaluate the signal-detection advantages and disadvantages that are implied by these two schemes: distortion product detection and cascading a signal through multiple layers of oscillator elements of different characteristic frequency. Last, we show that the combination of these two schemes yields a signal detector with enhanced frequency selectivity and speed of response, thus enabling the detection of transient, narrowband flight tones.
