The associations among platelet count, mean platelet volume, and erectile dysfunction: an observational and Mendelian randomization study.
Article in Sexual medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background: While previous studies have explored the associations and causalities among platelet count (PC), mean platelet volume (MPV), and erectile dysfunction (ED), further investigations are needed to clarify these relationships using advanced methodologies and analyzing specific populations. Aim: To investigate the associations and causalities among PC, MPV, and ED using observational study and Mendelian randomization (MR) analysis. Methods: A total of 114 patients with ED and 158 healthy control participants underwent a fasting blood draw to test for PC and MPV along with a comprehensive laboratory examination. The International Erectile Function Index was used to diagnose ED. Genetic variants of ED were obtained from individuals of European ancestry including 6175 ED cases and 217 630 controls. PC and MPV values were obtained from the UK Biobank and Investigating the effect of varying the whole blood inter-donation interval (INTERVAL) studies, encompassing a cohort of 173 480 individuals of European descent. Inverse-variant weighted (IVW), weighted median (WM), and MR-Egger methods were employed in MR analysis to explore the causal effects between variables to assess the impact of PC and MPV on ED. Various sensitivity analyses were employed to ensure the reliability of the results. Outcomes: Both observational study results and MR results revealed that elevated PC levels were associated with a heightened risk of ED, whereas reductions in MPV were linked to a decreased risk. Results: Logistic regression analysis indicated that an increased PC was associated with a greater risk of ED, with an odds ratio (OR) of 1.14 (95% CI: 1.08, 1.22; Clinical implications: In clinical work, it is an important guide for the prevention, diagnosis, and treatment of ED. Strengths and limitations: Our study employed a combination of observational studies and MR studies to strengthen our evidence. The observational study's sample size was relatively small, and MR was limited to individuals of European ancestry. Conclusion: A high PC and a low MPV are associated with an increased risk of ED, highlighting the importance of addressing platelet parameters in ED management.
