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
backgroundThe hypothalamic-pituitary-thyroid axis plays a crucial role in regulating metabolism and reproduction, yet its age- and sex-related dynamics in dromedary camels remain poorly understood.
objectiveThis study aimed to investigate age- and sex-dependent variations in pituitary thyrotroph morphometry and thyroid hormone profiles in dromedary camels.
methodsA total of 90 clinically healthy Brela breed camels of both sexes (aged 2 to ≥11 years) were grouped based on age and physiological status (lactating and non-lactating). Pituitary tissues (n = 60) were subjected to immunohistochemical analysis for thyroid stimulating hormone (TSH)-producing thyrotrophs. Morphometric parameters, including cell count, size, and nuclear dimensions, were measured. Plasma concentrations of TSH, triiodothyronine (T
resultsThyrotroph cell counts did not differ significantly among groups. However, older camels (≥11 years) showed significantly increased cell and nuclear dimensions (p < 0.05). Plasma TSH levels decreased with age, with peak levels observed in females aged 5-10 years. T
conclusionThyrotroph morphology and thyroid hormone dynamics in dromedary camels are significantly influenced by age and sex, indicating adaptive modulation of the hypothalamic-pituitary-thyroid axis in response to metabolic and reproductive demands.
