Enrichment of Cryptosporidium parvum from in vitro culture as measured by total RNA and subsequent sequence analysis.
Article in Molecular and biochemical parasitology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Cryptosporidium parvum is an apicomplexan parasite that infects a wide range of hosts including humans. Due to the parasite's quasi-intracellular, intermembrane location on the host cell, it is difficult to purify parasites from in vitro and in vivo infections for molecular studies. We have developed a method to greatly enrich in vitro C. parvum merozoites from host cells. The efficiency of the protocol was assessed with C. parvum (KSU-1 isolate) parasites of different developmental stages isolated following a synchronized infection of HCT-8 host cells. Total RNA was extracted from the samples and used to evaluate the quantity of host cell contamination in enriched parasite fractions. The quality of the RNA was verified using an Agilent BioAnalyzer. cDNA libraries of RNA isolated from 24 and 48 h C. parvum in vitro preparations isolated via this protocol were sequenced at the Broad Institute via an NIH Microbial Sequencing (GSCID) Contract. Cryptosporidium sequences comprised 30% of the cDNA reads, demonstrating significant enrichment.
