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

backgroundBroad-spectrum combination products with efficacy against endo- and ectoparasites offer the potential to optimize owner adherence to expert recommendations for canine antiparasitic treatments. In the development program for a chewable tablet containing fluralaner, moxidectin, and pyrantel, a non-terminal study design was implemented to determine anthelminthic efficacy. Four laboratory studies assessed the efficacy of this investigational veterinary product (IVP) against adult hookworms and adult Toxascaris leonina.

methodsIn four single-site, non-terminal dose confirmation studies, dogs were inoculated with third-stage larvae of Uncinaria stenocephala (Studies 1 and 2), Ancylostoma caninum (Study 3), or larvated eggs of T. leonina (Study 4). Using fecal egg counts (FECs) from those infections, dogs were ranked and randomized to groups (Studies 1, 3, and 4, 10 per group; Study 2, 8 per group and treated once orally, on day 0, with the minimum recommended IVP dose (fluralaner 10 mg/kg, moxidectin 0.025 mg/kg, pyrantel 5 mg/kg) (BRAVECTO

resultsAdequacy of infection was shown in all studies. Relative to the control groups, statistically significant reductions in mean worm counts were found in IVP-treated groups in Studies 1, 2, 3, and 4 (99.8%, P < 0.0001; 100%, P = 0.0002; 100%, P < 0.0001; and 99.4%, P < 0.0001, respectively). All control dogs had positive FECs until the DDW treatment, while no eggs were detected after day 0 in 36 of the 38 IVP-treated dogs. Findings from copro-PCR and antigen-ELISA were consistent with and confirmatory of the conclusions from worm counts and FECs.

conclusionsA single, orally administered dose of this chewable tablet formulation is effective in treating canine infections with adult hookworms (U. stenocephala, A. caninum) and T. leonina. Non-terminal studies present a valid means of determining the efficacy of anthelmintic treatments for these canine intestinal parasites.
