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

Background: One of the major challenges for malaria elimination is combating the highly efficient spread of the disease. Despite progress in understanding the development of malaria transmission stages, there remain many unanswered questions about how gametocytes transition from being immature to infectious. In Methods: We used a combination of phenotypic assays and transcriptional analysis to define the transition from immature non-infectious to mature infectious gametocyte. Specifically, we associated gene expression with distinct phenotypic traits: gametocyte deformability assessed by microsphere filtration, and gametocyte infectivity assessed by exflagellation and mosquito feeding assays. Conclusions: Our data revealed major transcriptional differences between input and deformable (i.e., filtered) gametocytes, but high similarity between deformable and infectious gametocytes. In combination with exflagellation and transmission results upon mosquito feeding assays, this suggests that deformable gametocytes are immediately infectious upon release from the bone marrow. The transcriptional analysis revealed a comprehensive set of infectivity markers that can be utilized to track gametocytes during their development and serve as diagnostic tools to map the human infectious reservoir.
