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

backgroundAfrican trypanosomosis is the disease caused by extracellular protozoan parasites of the genus Trypanosoma transmitted by tsetse flies. The current study has evaluated the trypanocidal activity of Commiphora swynnertonii extracts on Trypanosoma congolense.

methodsThe effect of ethanolic stem bark and resinous extracts on motility of T. congolense was evaluated by in vitro study at concentrations of 2 mg/ml and 4 mg/ml. Then, trypanocidal activity was evaluated by drug incubation infectivity test using mice at concentrations of 0.4 mg/ml and 2 mg/ml. In both studies negative (without drug) and positive (diminazene diaceturate) controls were used.

resultsThe in vitro study showed that, ethanolic stem bark extract of C. swynnertonii at concentration of 4 mg/ml caused complete cessation of motility for T. congolense in 30 min. However, resinous ethanolic extract had delayed effect on cessation of motility of T. congolense observed at 90 and 100 min post-incubation at concentrations of 4 mg/ml and 2 mg/ml respectively. The drug incubation infectivity test study depicted that ethanolic stem bark extract at concentration of 2 mg/ml significantly (p = 0.000) reduced the infectivity of T. congolense in mice. However, it did not vary significantly (P =0.897) with group treated with diminazene diaceturate incubated mixture.

conclusionThe current study has provided evidence that, ethanolic stem bark extract of C. swynnertonii possess trypanocidal activity against T. congolense. Based on these findings, further studies are recommended to determine its potential as a lead to trypanocidal drug discovery.
