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

We describe here a highly efficient procedure for conditional mutagenesis in Plasmodium. The procedure uses the site-specific recombination FLP-FRT system of yeast and targets the pre-erythrocytic stages of the rodent Plasmodium parasite P. berghei, including the sporozoite stage and the subsequent liver stage. The technique consists of replacing the gene under study by an FRTed copy (i.e., flanked by FRT sites) in the erythrocytic stages of a parasite clone that expresses the flip (FLP) recombinase stage-specifically--called the 'deleter' clone. We present the available deleter clones, which express FLP at different times of the parasite life cycle, as well as the schemes and tools for constructing new deleter parasites. We also outline and discuss the various strategies for exchanging a wild-type gene with an FRTed copy and for generating conditional gene knockout or knockdown parasite clones. Finally, we detail the protocol for obtaining sporozoites that lack a protein of interest and for monitoring sporozoite-specific DNA excision and depletion of the target protein. The protocol should allow the functional analysis of any essential protein in the sporozoite, liver stage or hepatic merozoite stages of rodent Plasmodium parasites.
