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
The use of face recognition based on numerous sketches is crucial for both law enforcement and digital entertainment. Due to lack of information given by the victim, it is difficult to identify faces from several sketches. In this study, we provide an unique SIFT (Scale Invariant Feature Transformation), 6-point facial landmark, Intuitionistic Fuzzy (IF) and Fuzzy [Formula: see text] oscillation based techniques. To improve accuracy of face recognition, we have used fuzzy based similarity measuring techniques called IF and Fuzzy [Formula: see text] oscillation. First, apply SIFT on sketches and digital pictures to find keypoints, then select the keypoints for extracting features. These values are classified using IF and fuzzy [Formula: see text] oscillation after feature extraction. Since we can get more than one image as output, so to overcome this problem we use a 6-point facial landmark detector (which is a modified facial landmark detector of 68-point facial landmark detector) for both the sketch and resulting digital images. Using these 6 points we draw two different regions for further verification. Two possibilities, which are presented at the beginning of Sect. 6, were taken into consideration for the experiment. As a result, by utilizing the provided method, matching a facial sketch to a photo will make it straightforward to identify the correct image. Experimental results shows that our approach achieved 95.1% accuracy for Fuzzy [Formula: see text] oscillation with SIFT domain and 97.3% for IF [Formula: see text] oscillation with SIFT domain. Our algorithm's accuracy suggested that IF and Fuzzy [Formula: see text] oscillation may be applied to the field of facial recognition-based sketching.
