Amazonian Anopheles with low numbers of oocysts transmit Plasmodium vivax sporozoites during a blood meal.
Article in Scientific reports, 2022. 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
Anopheles darlingi is the main malarial vector in the Brazilian Amazon region. An. nuneztovari s.l., An. triannulatus s.l., An. evansae, and An. benarrochi s.l. do not have a defined role as malarial vectors, although they have been found to be naturally infected with Plasmodium vivax, and some develop oocysts. In this study, we evaluated the importance of low numbers of oocysts in sporozoite salivary gland invasion and transmission. Field-collected mosquitoes were experimentally infected with P. vivax. The infection rates and oocyst and sporozoite infection intensities were evaluated and compared with those of An. aquasalis. We found the highest number of oocysts in An. darlingi (mean = 39.47) and the lowest in An. nuneztovari s.l. (mean = 2). The highest number of sporozoites was observed in An. darlingi (mean = 610) and lowest in An. benarrochi s.l. (mean = 30). Plasmodium vivax DNA was detected in the saliva of all mosquito species after a blood meal. Regardless of the number of oocysts, all species transmitted sporozoites during blood meals. Considering the abundance of these mosquitoes and transmission of sporozoites, it is logical to assume that An. nuneztovari s.l. and An. triannulatus s.l. are involved in the transmission of P. vivax.
