1 · What the graph read from it

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.

2 · The registry

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

Virophages parasitize the replication of co-infecting giant viruses within eukaryotic cells, forming tripartite cell-virus-virophage (CVv) systems. Tripartite interactions are well-documented in protozoa, yet comparable systems in algae remain largely unexplored at the experimental level. Here, we report an experimentally validated CVv system involving the green, single-celled microalga Chlorella sp. DSL01, Dishui Lake large algal virus 1 (DSLLAV1), and multiple Dishui Lake virophages (DSLVs). Inoculation of Chlorella sp. DSL01 at low MOI established laboratory co-cultures in which time-series PCR detected DSLLAV1 early but not after Day 10, whereas all tested virophages persisted. Metagenomic profiling of the terminal supernatant (end-point sample) indicated a virophage-dominated assemblage with DSLV3 most represented. Droplet digital PCR at discrete time points (Days 5, 10, and 15) then provided absolute counts for DSLLAV1 and DSLV1/3/7, corroborating an early DSLLAV1 peak followed by collapse and/or a delayed rise of multiple virophages coincident with host growth recovery. Nested PCR on the algal pellet detected virophages DSLV1/3/7 but not DSLLAV1. Together, these results demonstrate that Chlorella sp. DSL01 supports co-infection by DSLLAV1 and multiple virophages, establishing an experimentally validated algal CVv system and revealing multi-virophage participation in freshwater algal virus-virophage-host dynamics.
