Increased expression of PELP1 in human sperm is correlated with decreased semen quality.
Article in Asian journal of andrology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Proline-, glutamic acid-, and leucine-rich protein 1 (PELP1) is a scaffolding protein involved in both genomic and nongenomic estrogen signal transduction pathways. To date, the role of PELP1 protein has yet to be characterized in human sperm and has not been associated with sperm parameters. To confirm the presence of PELP1 in human sperm, fresh semen samples were obtained from 178 donors. The study was designed to establish both mRNA and protein presence, and protein cellular localization. Additionally, the number of PELP1-positive spermatozoa was analyzed in men with normal and abnormal semen parameters. Sperm parameters were assessed according to the World Health Organization (WHO) 2010 standards. The presence of PELP1 in spermatozoa was investigated using four precise, independent techniques. The qualitative presence of transcripts and protein was assessed using reverse transcription-polymerase chain reaction (RT-PCR) and western blot protocols, respectively. The cellular localization of PELP1 was investigated by immunocytochemistry. Quantitative analysis of PELP1-positive cells was done by flow cytometry. PELP1 mRNA and protein was confirmed in spermatozoa. Immunocytochemical analysis identified the presence of PELP1 in the midpieces of human sperm irrespective of sperm parameters. Becton Dickinson fluorescence-activated cell sorting (FACSCalibur™) analysis revealed a significantly lower number of PELP1-positive cells in males with normal semen parameters versus abnormal samples (42.78% ± 11.77% vs 61.05% ± 21.70%, respectively; P = 0.014). The assessment of PELP1 may be a time-saving method used to obtain information about sperm quality. The results of our study suggest that PEPL1 may be utilized as an indicator of sperm quality; thereby, PELP1 may be an additional biomarker useful in the evaluation of male infertility.
