Subclinical Pregnancy Toxemia Affects Blood Parameters of Ewes and Impairs Postnatal Growth and Development of Lambs.

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
Pregnancy toxemia (PT) is a common metabolic disorder that occurs in the last trimester of pregnancy. This study aimed to detect the effects of subclinical PT (SPT) on serum biochemical parameters of ewes and postnatal growth and development of lambs in Romanov sheep. A total of 40 ewes and 69 lambs were included in the study. Blood samples of ewes were collected at the time of parturition to evaluate serum beta-hydroxybutyric acid (βHBA), serum nonesterified fatty acid (NEFA), cholesterol, and triglyceride. Live weight and body measurements of lambs were recorded at birth (0th day), 30th day, and 60th (weaning) day. In the diagnosis of SPT serum βHBA concentrations were taken into account. A cut-off value of 0.8 mmol/L for βHBA was a critical concentration and ewes with 0.8-1.6 mmol/L βHBA were evaluated as SPT. There were no ewes with ΒHBA value higher than 1.6 mmol/L (clinical PT) in the study. There was no significant difference in serum βHBA, NEFA and cholesterol concentrations between ewes regarding birth type (single, twin, and triplet). However, triglyceride concentrations were higher (p < 0.001) in ewes giving birth to triplets compared to ewes giving birth to single lamb. Serum βHBA and triglyceride concentrations were higher (p < 0.01) in ewes with SPT (n = 14) compared to healthy ewes (n = 26). There was no significant difference between ewes with SPT and healthy ewes in serum NEFA and cholesterol. Repeated measures ANOVA results indicated that SPT negatively affected 0th, 30th, and 60th body weights of twin (p < 0.01) and triplet born lambs (p < 0.05). The effect of time on body weights was also found to be significant (p < 0.001). Similarly, most of the body measurements of twin and triplet born lambs were lower (p < 0.05) in the SPT group compared to healthy group. Overall results indicate that SPT may negatively affect postnatal growth and development in Romanov lambs. Because a decline in growth performance has many negative outcomes affecting production traits in sheep, these findings may be valuable for the veterinary field.
