Morphological variations of the human spleen: no evidence for a multifocal or lobulated developmental origin.

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
objectivesAdult spleens show extensive morphological variation, with a reported prevalence of 40-98% clefts (also called notches or fissures) on the splenic surface and 10-30% accessory spleens at autopsy. It is hypothesised that both anatomical variants result from a complete or partial failure of multiple splenic primordia to fuse to the main body. According to this hypothesis, fusion of the spleen primordia is completed after birth and spleen morphological variations are often explained as stagnation of spleen development at the foetal stage. We tested this hypothesis by studying early spleen development in embryos, and compared foetal and adult spleen morphology. METHODS AND MATERIALS: We assessed 22 embryonic, 17 foetal and 90 adult spleens on the presence of clefts using histology, micro-CT and conventional post-mortem CT-scans, respectively.
resultsThe spleen primordium was observed as a single mesenchymal condensation in all embryonic specimens. The number of clefts varied from 0 to 6 in foetuses, compared to 0-5 in adults. We found no correlation between foetal age and number of clefts (R
conclusionWe found no morphological evidence for a multifocal origin or a lobulated developmental stage of the human spleen. ADVANCES IN KNOWLEDGE: Our findings show that splenic morphology is highly variable, independent of developmental stage and age. We suggest to abandon the term "persistent foetal lobulation" and to regard splenic clefts, regardless of their number or location, as normal variants.
