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

This report describes a method for growing both bloodstream- and procyclic-form Trypanosoma brucei as colonies on agarose plates. Procyclic colonies, which took 2 weeks to develop, grew with approximately 17% plating efficiency on SDM-79/0.65% agarose supplemented with 20% (vol/vol) conditioned medium. Bloodstream forms were adapted to in vitro growth in liquid HMI-9 medium and then spread on HMI-9/0.65% agarose plates, where they grew to visible colonies in 3-5 days. Plating efficiencies were from 3 to 80%, depending upon the trypanosome variant and experiment. Colonies were proven to be the result of growth from a single cell and contained approximately 10(6) cells at maturity. Colonies were transferred to filters and probed for multicopy and single-copy genes. Potential uses of this method in conjunction with classical and reverse genetic approaches to studying trypanosomes are discussed.
