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

Conjoined twins are rare and present significant challenges for surgical and anesthetic teams. Pygopagus twins, fused at the pelvis and lower spine, require meticulous planning, and multidisciplinary collaboration. This report describes the elective separation of pygopagus twin girls, involving advanced imaging, 3D anatomical modeling, and simulation-based preparation. A color-coded system differentiated anesthesia teams, equipment, and monitors, ensuring clarity during the 27-h procedure. Anesthesia was maintained with sevoflurane and remifentanil, with individualized fluid and hemodynamic management. Surgical steps included separation of shared spinal, rectal, and urogenital structures, followed by soft tissue reconstruction. The surgery was completed without major complications. Both twins were extubated within seven days, recovered well in the pediatric ICU, and were discharged on postoperative day 56 without neurological deficits. This case highlights the value of thorough planning, advanced imaging, and a structured multidisciplinary approach. Color-coded systems and simulations enhanced coordination, reduced risks, and improved outcomes.
