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
purposeSex chromosome abnormalities are associated with male infertility. The aim of this study was to characterize the clinical, cytogenetic, and molecular findings of 12 infertile men with isodicentric Y-chromosome [idic(Y)] abnormalities diagnosed over a period of 13 years. MATERIALS AND
methodsChromosomal analyses of peripheral blood samples were done using standard procedures. Fluorescence in situ hybridization (FISH) analysis was performed on metaphase spreads of the patients. Multiplex polymerase chain reaction (PCR) using several sequence-tagged site (STS) primer sets within the long arm of Y-chromosome was used to detect AZF deletions.The breakpoints and copy number variations (CNV) were identified by array comparative genomic hybridization analysis (aCGH) analysis.The short-stature homeobox (SHOX) gene deletions were verified using multiplex ligation-dependent probe amplification (MLPA) analysis.
resultsTwelve infertile men were diagnosed cytogenetically with idic(Y). The karyotypes of two of the patients were non-mosaic, and the remaining karyotypes showed various degrees of mosaicism. SHOX gene deletion was found in two of the four patients with short stature, and the remaining two patients had shown a 45,X dominant cell line (33.3%). The most common breakpoints for idic(Yq) and idic(Yp) were found to be in Yq11.222 and Yp11.32, respectively. Semen analysis of ten patients (83.3%) demonstrated azoospermia, and the remaining two patients (16.7%) showed severe oligoasthenoteratozoospermia (OAT). In total, 33% (4/12) of idic(Y) patients with or without microsurgical testicular sperm extraction (microTESE) had sperm retrieval.
conclusionsTwelve patients with idic(Y) and different breakpoints of Y-chromosome were characterized using multiple detection strategies. Sperm retrieval outcomes of patients either with idic(Yp) or idic(Yq) showed the possibility to find sperm by microTESE.
