Effects of leaf extracts of Protium spruceanum against adult and larval Rhipicephalus microplus.
Article in Experimental & applied acarology, 2019. 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
Rhipicephalus microplus is the ectoparasite responsible for large economic losses in cattle herds. The aim of this study was to investigate the in vitro action of leaf extracts of Protium spruceanum on resistant strains of this tick. Ethanolic extracts (EE) and ethyl acetate extracts (EAE) of P. spruceanum leaves were used against engorged females and larvae by biocarrapaticidogram and larval package (TPL) tests. Chromatographic analyses were performed using a gas chromatograph and showed the presence of the flavonoid catechin in both extracts and the terpenoid β-amirine only in EAE. EE and EAE were not effective in altering the mortality of engorged females; however, 92% of females treated with the extracts reduced the postures and > 90% of larval hatching was inhibited at 100 mg/ml of extracts. Acaricidal efficacies were > 80% for 100 mg/ml EE and > 90% for EAE at 50 mg/ml. In TPL tests, EE and EAE promoted larval mortality > 88% at 100 mg/ml. In this study, EAE was more effective against adult females and larvae than EE, representing an alternative agent for the integrated control of R. microplus.
