1 · What the graph read from it

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.

2 · The registry

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

Limited dorsal myeloschisis (LDM) and spinal dermal sinus tracts (DST) are rare forms of closed spinal dysraphism that are usually considered distinct entities, and their coexistence with a dermoid cyst is exceptionally uncommon. We describe a 3-month-old female infant with a congenital lumbosacral swelling; MRI revealed a subcutaneous cyst with imaging features suggestive of an epidermoid-type lesion, a fibro-neural stalk, and associated tethered cord, syrinx, and dorsal tenting. The patient underwent complete excision of the cyst and removal of the fibro-neural stalk along with its dural attachment site, followed by untethering; histopathology confirmed coexisting LDM and DST with a dermoid cyst. This case highlights that although LDM and DST have distinguishable features, they may rarely coexist, and complete resection of the stalk, including its dural insertion, is essential to prevent infection and ensure that an associated DST is not missed.
