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

Paramphistomosis, a parasitic disease of ruminants caused by flukes of the family Paramphistomidae (Platyhelminthes: Digenea) and leads to significant economic losses. Primarily, their predilection site is rumen as evident from their common name 'ruminal flukes' and occasionally find in other visceral organs. This study aimed to determine the prevalence of paramphistome infection in the rumens and livers of livestock followed by histopathological examination of the affected tissues. A total of 384 animals were screened for paramphistome infection at a local abattoir in the Narowal district. Liver and rumen tissue samples from infected animals were excised, fixed in buffered formalin, and processed using the paraffin-embedding technique. Tissue-paraffin blocks were sectioned with the thickness of 5 µm through microtome and stained using the Harri's haematoxylin and eosin methods. The prevalence of paramphistomosis in ruminants was 49.74% with sex and age of host having a statistically significant association (p < 0.05) with the magnitude of infection; however, species of host and months were not significantly associated (p > 0.05). Of the total cases having rumens positive for paramphistomes, 7.29% were also tested positive for liver infections; however, no adult or immature Fasciola spp. were detected. Infected rumens had significantly (p < 0.05) reduced epithelial thickness (30.50 ± 1.83 µm), accompanied by severe haemorrhages in hepatic tissues and blood congestion in hepatic vessels. Further, the central hepatic vein was found having a significantly larger diameter (39.56 ± 2.72 µm) as compared to that of healthy livers (29.76 ± 3.15 µm). The paper provides a maiden data on the paramphistome infection in livers along with rumens of ruminants in Pakistan. Hence, the findings suggest that paramphistome infection may pose a potential threat to nutrient absorption and overall metabolic health in ruminants.
