Quantitative Distribution of Infectious F-Specific RNA Phage Genotypes in Surface Waters.
Article in Applied and environmental microbiology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
unlabelledF-specific RNA phages (FRNAPHs) are considered potential viral indicators of water pollution due to their occurrence and stability in water environments. However, their suitability as viral indicators is not fully elucidated because the characteristics of FRNAPHs are variable depending on the genotype. In this study, for the characterization of infectious FRNAPH genotypes, integrated culture reverse transcription-PCR coupled with the most probable number approach was applied to surface water samples. Further, to recover low concentrations of FRNAPH genotypes, an FRNAPH recovery method was developed. The novel FRNAPH recovery method using a noncharged microfiltration membrane could effectively recover FRNAPH strains without inactivation, while a method using an electronegative microfiltration membrane resulted in the inactivation of some strains. Infectious FRNAPH genotypes in surface water samples were successfully quantified with an efficiency comparable to that of the conventional plaque assay. Genotype I (GI) and GII FRNAPHs tended to be predominant at locations impacted by treated and untreated municipal wastewater, respectively. The numbers and proportions of infectious FRNAPHs tended to be higher during the winter season when water temperature decreased. IMPORTANCE: Properties of FRNAPHs are highly variable depending on their genotypes. Previous typing methods for FRNAPHs are not quantitative and/or are based on molecular assays, which cannot differentiate infective strains from inactive strains. Due to the reasons mentioned above, the utility of FRNAPHs as viral indicators of water pollution has not been fully validated. In this study, a quantitative genotyping method for infectious FRNAPHs was developed and applied to surface water samples. The method enabled characterization of infectious FRNAPH genotypes in terms of their occurrence and seasonality. Moreover, comparison of the method to a conventional molecular assay (reverse transcription-quantitative PCR) enabled characterization of their stability. Our approach can provide novel findings for further validation of FRNAPHs as viral indicators of water pollution.
