Collection and Cryopreservation of Plasmodium falciparum Clinical Isolates in the Field.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
P. falciparum causes the most severe form of malaria in younger children and pregnant women. In vitro culture systems allow researchers to understand parasite biology, elucidate mechanism of host immunity and test efficacy of antimalarial agents or vaccines in preclinical studies. Most laboratory-adapted parasite strains predate the emergence of artemisinin-based drug combinations and mainly originate from Asia or Europe. To fully understand the biochemical and phenotypic characteristics of parasites, it is imperative that researchers are able to culture parasites circulating in an area to unravel any geographical differences at the population level. Ex vivo culturing of clinical isolates can be challenging when collecting samples in the field and requires technical expertise and equipment. To overcome this challenge, clinical isolates are cryopreserved in the field and transported to a laboratory for in vitro studies. In this protocol, we describe different methods of cryopreserving P. falciparum isolates in the field and thawing them for subsequent in vitro culture.
