SMOKING EFFECT ON OXIDATIVE STRESS AND ANTIOXIDANT CAPACITY OF CERVICAL MUCUS IN WOMEN WITH PRIMARY IDIOPATHIC STERILITY - OBSERVATIONAL CASE-CONTROL STUDY.
Observational study in Acta clinica Croatica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The aim of the study was to determine the effects of smoking on cervical mucus in women with primary idiopathic sterility. A prospective, case-control, observational, quantitative, and analytical study was carried out over a five-year period through ambulatory care. The first part of the study involved 140 healthy women (85 smokers and 55 non-smokers). The second part included 90 women (58 healthy, 32 suffering from sterility), grouped according to their smoking status. Concentrations of total proteins in cervical mucus solutions and homogenates of cervical surface cells and their mitochondria, thiocyanate and ascorbic acid, rhodanese activity, concentrations of cytochrome P-450 (mitochondria), lipid peroxidation and the total antioxidant capacity in homogenates of cervical surface cells, concentrations of superoxide O2, reduced gluthatione (GSH), advanced oxidation protein products (AOPP), and ferric reducing ability of plasma (FRAP) were measured. The measurements showed higher concentrations of thiocyanate, cytochrome P-450 and lipid peroxidation values, and lower concentrations of ascorbic acid, cytochrome P-450 activity and FRAP in smokers. Higher concentrations of superoxide O2, GSH, AOPP, and lower FRAP were found among smokers and women suffering from sterility. In conclusion, changes in oxidative stress and antioxidant capacity caused by smoking indicate that the quality of cervical mucus among patients suffering from sterility is lower compared to healthy women.
