Goats are more susceptible to Haemonchus contortus infection than sheep under similar experimental settings.

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
Due to differences in their feeding behavior, sheep and goats are often assumed to respond differently to helminth infections. The present study compared Haemonchus contortus infection profile between sheep and goats under the same experimental setting. Experimental infection was conducted using a randomized block design in four groups of intact sheep (InfSH and ConSH) and goats (InfG, and ConG). Groups InfSH and InfG (N = 7 each) received 10,000L3 of H. contortus whereas the control groups ConSH and ConG (N = 7 each) remained uninfected. Faecal egg counts and PCV were measured from Day 0 to day 56 post infection (PI). On day 56 PI, animals were humanely slaughtered and abomasal contents were recovered to measure worm burden, worm length and in utero egg count. The findings show that: (1) Haemonchus infected animals showed an increase in FEC starting from day 21 PI, (2) progressive reduction in PCV was registered from day 7 PI and continued to the end of the experiment while this remained at pre-infection levels in control groups, (3) FEC was much higher (P < 0.001) and PCV was significantly lower (P < 0.05) in infected goats than in infected sheep, (4) at necropsy, total worm burden with worm establishment rates of 63% and 28.87% were registered respectively for infected goats and sheep with significant difference (P < 0.05), (5) Female worms were significantly longer (P < 0.05) in InfG (22.8(± 1.2) compared to InfSH (20.5 ± 0.67 mm) while (6) Mean worm fecundity was 974.8 ± 239.4 and 1162.5 ± 89.4 respectively for groups InfSH and InfG with no significant difference (P = 0.07), and (7) Parasite traits such as worm burden, FEC and female worm length were well correlated in sheep whereas few such patterns were observed in goats. In conclusion, under the same experimental infection, Arsi-Bale goats are more susceptible to H. contortus infection than Arsi-Bale sheep and hence deserve special attention when they are forced to live on grazing rather than browsing.
