Screening of Sceptridium ternatum for antitussive and antiasthmatic activity and associated mechanisms.
Article in The Journal of international medical research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Objectives Sceptridium ternatum is an expectorant in traditional Chinese medicine and is prescribed for the treatment of asthma. The study aim was to screen Sceptridium ternatum for ingredients with antitussive and antiasthmatic effects and to study their associated mechanisms. Methods Cough in mice was induced using ammonia. Cough latency and the number of coughs within 3 minutes were determined. Airway responsiveness was assessed using ovalbumin as a sensitizer and characteristic asthma indicators were measured. Results Chloroform and ethyl acetate extracts significantly reduced the number of coughs within 3 minutes, tidal volume, and the percentage of eosinophilic granulocytes, lymphocytes and neutrophils. All extracts decreased airway responsiveness in asthmatic mice compared with the untreated group. Petroleum ether, chloroform and n-butanol extracts lowered the Penh values of asthmatic mice. Petroleum ether and ethyl acetate extracts greatly reduced interleukin-4 expression and the interleukin-4/interferon gamma ratio. Compared with the model group, all extracts reduced mRNA expression of the cysteinyl leukotriene receptor-1 (CysLT
