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

The study was aimed at investigating temporal changes in body weight and blood profiles of related metabolites in rangeland sheep raised under an extensive production system. Body weight measurements were taken every month using a sheep crate electronic weighing scale and pooled to represent each season. Approximately 5 ml blood samples were collected from 262 ewes for serum biochemical analysis using standard procedures. The data were analyzed by univariate ANOVA in a completely randomized design with year (2012, 2013), age (4, 6, 8 years), and season (autumn, winter, spring, summer) as fixed factors and animal as a random variable. The body weight (BW), glucose, globulin, and albumin/globulin (A/G) ratio levels varied (P<0.05) between years. Older ewes (8 years) showed significantly higher (P<0.05) blood glucose levels compared to younger ewes (4 and 6 years). The total protein (TP), albumin, globulin, calcium and phosphorus contents were all higher (P< 0.05) in winter and spring compared to autumn or summer, while urea was high in spring and summer (P<0.05). The physiological status significantly (P<0.05) influenced BW, glucose, TP, albumin, globulin, cholesterol, calcium, and phosphorus levels of sheep. The BW was negatively correlated to most serum components. It was concluded that autumn and summer seasons are associated with improved body weight gains due to increased forage availability and quality, while higher levels of total protein, albumin, and globulin are observed in winter and spring, reflecting the animals' metabolic adaptations to varying environmental conditions.
