Highly diluted medication reduces parasitemia and improves experimental infection evolution by Trypanosoma cruzi.
Article in BMC research notes, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundThere is no published information about the use of different protocols to administer a highly diluted medication.Evaluate the effect of different protocols for treatment with biotherapic T. cruzi 17 dH (BIOT(Tc17dH)) on clinical/parasitological evolution of mice infected with T. cruzi-Y strain.
methodsA blind, randomized controlled trial was performed twice, using 60 28-day-old male Swiss mice infected with T. cruzi-Y strain, in five treatment groups: CI - treated with a 7% ethanol-water solution, diluted in water (10 μL/mL) ad libitum; BIOT(PI) - treated with BIOT(Tc17dH) in water (10 μL/mL) ad libitum during a period that started on the day of infection; BIOT(4DI) - treated with BIOT(Tc17dH) in water (10 μL/mL) ad libitum beginning on the 4th day of infection; BIOT(4-5-6) - treated with BIOT(Tc17dH) by gavage (0.2 mL/ animal/day) on the 4th, 5th and 6th days after infection; BIOT(7-8-9) - treated with BIOT(Tc17dH) by gavage (0.2 mL/ animal/day) on the 7th, 8th and 9th days after infection. We evaluated: parasitemia; total parasitemia (P(total)); maximum peak of parasites; prepatent period (PPP) - time from infection to detection of the parasite in blood; patent period (PP) - period when the parasitemia can be detected in blood; clinical aspects; and mortality.
resultsParasitological parameters in the BIOT(PI) and mainly in the BIOT(4PI) group showed better evolution of the infection compared to the control group (CI), with lower P(total), lower maximum peak of parasites, higher PPP, lower PP and longer survival times. These animals showed stable body temperature and higher weight gain and water consumption, with more animals having normal-appearing fur for longer periods. In contrast, groups BIOT(4-5-6) and BIOT(7-8-9) showed worse evolution of the infection compared to the control group, considering both parasitological and clinical parameters. The correlation analysis combined with the other data from this study indicated that the prepatent period is the best parameter to evaluate the effect of a medication in this model.
conclusionsThe BIOT(4DI) group showed the best clinical and parasitological evolution, with lower parasitemia and a trend toward lower mortality and a longer survival period. The prepatent period was the best parameter to evaluate the effect of a medication in this model.
