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

backgroundAnti-malarial herbal preparations (HPs) continue to enjoy high patronage in Ghana despite reports that the artemisinin-based combination therapy (ACT), the recommended first choice for treatment of uncomplicated malaria in the country, remains efficacious. A major issue with the use of these preparations is inadequate or unreliable data on their efficacy and quality. An assessment of the potency and quality of the most popular commercial anti-malarial HPs in Ghana was, therefore, carried out. The outcome of this investigation is herein discussed preceded by a short literature review of herbal medicines in Ghana.

methodsUsing a questionnaire survey of 344 individuals in parts of Ghana, five of the most frequently used HPs were identified and selected for test of their efficacy and quality. The effect of the selected compounds on Plasmodium berghei in vivo was assessed using standard methods.

resultsAll five tested HPs (HP-A, HP-B, HP-C, HP-D and HP-E) showed chemo-suppressive activity against P. berghei in vivo. However the degree of parasites inhibition is significantly lower compared to the WHO-recommended artemether-lumefantrine combination (p < 0.05, 99.9% chemosuppression/activity, 28 days survival). Using the Solomon Saker's Test, two of the preparations were found to contain chloroquine or compounds with chemical properties like that of chloroquine.

conclusionPopular anti-malarial HPs used in southern Ghana were found to have chemo-suppressive properties. Intentional addition of chloroquine or SCs to these preparations in order to enhance their effectiveness has serious public health concerns as it may induce cross resistance to amodiaquine, one of the partner drugs in the recommended ACT for use in Ghana.
