Tear Film Osmolarity in Horses With Bacterial Conjunctivitis.
Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundConjunctivitis is an inflammation of the conjunctiva caused by infectious or non-infectious factors. Infectious conjunctivitis comes in two forms: viral and bacterial. Bacterial conjunctivitis is commonly caused by organisms such as Staphylococcus and Streptococcus, with the severity of the disease influenced by the specific bacterial species involved. Because both viral and bacterial conjunctivitis are highly contagious, preventive measures are essential to reduce transmission-especially to the unaffected eye.
objectiveTo evaluate the tear film osmolality in horses with bacterial conjunctivitis.
methodsA total of 40 healthy horses and those with conjunctivitis were included in the study. Tear samples were collected from both eyes with microcapillary tubes three times at 5-min intervals. The tear samples for each horse were pooled, and the osmolality and electrolyte concentrations were measured. The mean (SD) was calculated for each variable to establish preliminary guidelines for tear film osmolality and electrolyte composition in healthy horses.
resultsThe mean (SD) tear film osmolality was 283.51 (9.33) mmol/kg, and the mean (SD) sodium, potassium, magnesium and calcium concentrations were 134.75 (10), 16.3 (5.77), 3.48 (1.97) and 1.06 (0.42) mmol/L, respectively. The sodium concentration in the tear film was similar to that in serum, whereas the potassium concentration in the tear film was approximately 4.75 times that of serum.
conclusionsMeasuring tear-film osmolality offers a non-invasive, easy and practical approach to gaining valuable insights into baseline conditions and potential changes in ocular diseases. However, its true clinical utility requires integration with other ocular parameters and further controlled studies in horses suffering from conjunctivitis. The development of such tools could lead to more accurate diagnoses and more comprehensive treatment strategies.
