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
objectiveThe aim of this study was to compare narrow band imaging (NBI) endoscopy and Storz Professional Image Enhancement System (SPIES) in observing epithelial and/or subepithelial microvascular irregularities and pathologies.
methodsA total of 73 patients with laryngeal or hypopharyngeal lesions were investigated using high-definition NBI endoscopy preoperatively in local anesthesia and using SPIES system intraoperatively in general anesthesia from August 2016 to October 2017. Superficial vascular structures were classified preoperatively (NBI) and intraoperatively (SPIES) according to descriptive guidelines of vascular changes by Arens. All lesions were endoscopically evaluated and divided according to the histological examination into four groups (A-benign lesions, B-recurrent respiratory papillomatosis, C-low-grade dysplasia, D-high-grade dysplasia, carcinoma in situ or invasive squamous cell carcinoma), and results were compared with NBI and SPIES optical biopsy.
resultsBenign lesions (polyps, cysts, chronic inflammation, hyperkeratosis) were histologically confirmed in 26/73 (35.6%) cases and identified by NBI in 20/26 lesions (76.9%) and in 20/26 cases (76.9%) by SPIES, respectively. Recurrent respiratory papillomatosis was confirmed in 16/73 (21.9%) and detected in 15/16 cases (93.8%) by NBI and in 16/16 cases (100.0%) by SPIES. Low-grade dysplasia (mild and moderate dysplasia) was histologically detected in 7/73 patients (9.6%) and accurately identified by NBI in 6/7 (85.7%) and by SPIES in 6/7 (85.7%) cases, respectively. Histopathological features of severe dysplasia, carcinoma in situ or invasive squamous cell carcinoma were detected in 24/73 (32.9%) patients. According to the NBI endoscopy the suspected vascular neoangiogenesis was recognized in 19/24 cases (79.2%) and in 18/24 cases (75.0%) using SPIES endoscopy. Sensitivity and specificity of NBI endoscopy and SPIES system in correct prediction of histological diagnosis of already detected lesions were 83.0 and 98.0% and 86.0 and 96.0%, respectively. Results of NBI/SPIES endoscopy and histopathological features of laryngeal and hypopharyngeal lesions were compared and the level of agreement was 81.43%, kappa index κ = 0.7428 (95% CI 0.682-0.832) (p < 0.001) by NBI endoscopy and 81.16%, kappa index κ = 0.7379 (95% CI 0.638-0.880) (p < 0.001) by SPIES endoscopy, respectively. The agreement was confirmed as substantial and strong. Level of agreement of both endoscopic methods was 92.54%, kappa index κ = 0.8965 (95% CI 0.877-0.954) (p < 0.001), agreement was confirmed as almost perfect. Between NBI and SPIES endoscopic imaging methods is no significant differentiation.
conclusionBoth methods, NBI endoscopy and SPIES system, are comparable in detection and analysis of superficial neoangiogenesis, typical for benign lesion and for precancerous or cancerous changes in larynx and hypopharynx.
