Microsurgical anatomy of the spinal cord in human fetuses.

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
purposeTo determine the microsurgical features of the spinal cord and ventral and dorsal rootlets in fetal period.
methodsTwelve formalin-fixed fetuses (six females and six males) with a mean gestational age of 27.0 ± 2.04 weeks (range between 25 and 32 weeks) were dissected to evaluate morphological properties of the spinal cord and rootlets.
resultsLength and width of each spinal cord segment, number of dorsal and ventral rootlets, length of dorsal root entry and ventral root exit zones of each spinal nerve, spinal cord termination level, and the whole spinal cord length were determined in all fetuses. Contrary to previous reports, the number of ventral rootlets was always more than that of dorsal rootlets in all segments. No statistically significant gender difference was found for all parameters. Rootlet number and segment width in cervical region were larger than those of thoracic, while the lengths of dorsal root entry and ventral root exit zones in thoracic region were longer than those of cervical. In lumbar region, dorsal and ventral rootlet numbers were increasing again, while lengths of dorsal root entry and ventral root exit zones were decreasing. Number of dorsal and ventral rootlets of C5 and C6 segments was statistically higher than other cervical segments. The mean spinal cord length was found as 105.55 ± 11.30 mm and there was a positive significant relationship with gestational age. Conus medullaris level was detected between L1 and L3 segments.
conclusionDetailed microsurgical data about the fetal spinal cord and the dorsal and ventral rootlets presented in this study provide significant information which may be essential during surgical interventions in early postnatal period and childhood targeting the spinal cord and spinal nerve roots.
