The correlation between abnormal Krüger strict morphology and the sperm DNA fragmentation index.
Article in JBRA assisted reproduction, 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
objectiveThis study aims to investigate whether alterations in sperm DNA fragmentation rates are more frequent when Krüger strict morphology is ≥4% (normal).
methodsThe retrospective study included 132 participants from March 2020 to November 2021. Participants were divided into two groups based on the inclusion criteria: normal and abnormal Krüger strict morphology, with a mean age of 40 years. Seminal analyses were conducted following the guidelines outlined in the 6th edition of the Manual for Examination and Processing of Human Semen (2021). The sperm chromatin dispersion test was used.
resultsThe results did not reveal a statistically significant difference between Krüger strict morphology and Sperm DNA Fragmentation Index correlation (p<0.05) between the normal and abnormal morphology groups (p<0.05) and in Seminal Parameters. Sperm concentration is lower when Krüger strict morphology is < 4% (abnormal) (p=0.007).
conclusionsIn conclusion, abnormal Krüger strict morphology does not have a higher predisposition to increased sperm DNA fragmentation.
