Cellular reactions in capillary and venous blood in northerners to a short-term period in a climatic chamber.

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
purposeThe purpose is a comparative study of the cellular reactions in capillary and venous blood in northerners under general hypothermia in a climatic chamber during different photoperiods. The authors examined 108 relatively healthy people (80 women and 28 men aged 21- to 50-years old).
methodsThe study included determining the hemogram, neutrograms, monocytograms, lymphocytograms, and phagocytic activity neutrophil granulocytes, enzyme immunoassay, flow cytometry, indirect immunoperoxidase, bioluminescence, systolic and diastolic blood pressure, and body temperature in the ear canal and on the skin of the rear left side of the right hand of volunteers before the effect of general cooling in the room at an air temperature and after 5 minutes of exposure to cold air.
resultsIt was established that total neutrophil count in venous blood was lower by 8.07% ± 0.41%, monocyte count by 51.32% ± 1.03%, and basophil count by 50.21% ± 1.24% than in capillary blood, but the lymphocyte count was higher by 25.23% ± 0.41% due to smaller forms that are known to be recirculating. After a 5-minute period in a climatic chamber at -25°C in 27.53% of individuals during a polar night and in 16.51% volunteers during a polar day had elevated levels of neutrophils in the venous blood due to the increase in the levels of tumor necrosis factor-α in blood and decrease in noradrenaline, adrenaline, and irisin.
conclusionThe systematic effect of general cooling, especially during the polar night, leads to a reduction in reserve adaptability with the formation of neutropenia, deficiency of phagocytic defense, and functional insufficiency of T-lymphocytes.
