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
Milk at a normal state has unique physical, chemical, and biological characteristics that are used as quality indicators. The quality of milk is influenced by many factors and the components of milk are very sensitive indicators for milk production practices. Season and agro-ecologies have influences on physicochemical properties of cow milk. Therefore, this research aimed to investigate the effect of season and agro-ecology on the physicochemical properties of cow's raw milk in Central and North-Western Zone of Tigray. The study was conducted in Aksum, Shire-Indaselassie, and Sheraro administrative towns. A two-stage sampling method was used to select both the study area and respondents. All towns in the Central and North-Western zones of Tigray were categorized into three agro-ecologies, and sample towns were purposively selected from each category based on accessibility and milk production potential. Sample respondents were then randomly selected from each agro-ecology. Agro-ecology categorization was based on altitude, temperature, and feeding practices, while seasons were classified according to rainfall and temperature. A total of 210 samples, comprising 35 samples from dairy farms and 35 samples from cafeterias within each agro-ecology, were analyzed to assess the physicochemical properties of cow milk across two different seasons. Physicochemical analysis including determination of fat, crude protein, solids not fat, density, lactose, salt, water added and freezing point was conducted in the laboratory of Mekelle University using Lacto scan, Bulgaria. The overall mean values of milk fat, solids-not-fat (SNF), protein, and lactose were 3.72 ± 0.12 %, 6.72 ± 0.17 %, 2.6 ± 0.08 %, and 3.72 ± 0.09 %, respectively. Specific gravity, salt content, water added, and freezing point exhibited mean values of 1.026 ± 0.001 g/ml, 0.53 ± 0.01 %, 19.33 ± 1.8 %, and -0.42 ± 0.01
