The effects of tobacco consumption on paternity rates of adults with a history of cryptorchidism.
Article in Pediatric surgery international, 2020. 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
objectiveTo determine the effect of tobacco consumption on paternity rates in men with a history of cryptorchidism. To compare the paternity rates between formerly unilateral, bilateral cryptorchid smokers, and nonsmokers.
methodsA retrospective cohort study of 153 men who had undergone orchiopexy between 1961 and 1985 at the Miguel Servet University Hospital (116 unilateral and 37 bilateral) and a control group of 100 men were evaluated by review of medical records and a questionnaire.
resultsA total of 197 men filled the questionnaire (76.7%). There was no difference in paternity rates between smokers compared to nonsmokers (P = 0.21). In the unilateral cryptorchid men (ULC) group, there is no difference in paternity rates when compared with the controls (P = 0.079) or when comparing ULC smokers to ULC nonsmokers (P = 0.35). In the bilateral cryptorchid men (BLC) group, there is no difference in paternity rates when compared to controls (P = 0.075) or when comparing BLC smokers to BLC nonsmokers (P = 0.36). When comparing according to consumption, there is no difference between mild, moderate or heavy smoker cases and controls.
conclusionThere is no difference in paternity rates between men with a history of cryptorchidism that consume tobacco compared to nonsmokers or controls. More studies are needed to determine the impact of tobacco consumption in formerly cryptorchid men.
