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

We conducted a prospective, randomized study to compare the safety and efficacy of using a conventional nephrostomy sheath (CNS) versus a minimally invasive suction-evacuation nephrostomy sheath (SENS) for treating partial staghorn stones. Eighty-six patients with partial staghorn stones were randomly assigned into two groups, with 43 patients in each group. One group underwent standard percutaneous nephrolithotomy (sPCNL) using CNS, whereas the other group underwent minimally invasive percutaneous nephrolithotomy (mPCNL) with SENS. Patient demographics, stone characteristics, intraoperative data, perioperative data, and surgical results were collected and analyzed.The patient demographics and stone characteristics were similar in both groups. The SENS group had significantly lower peak and mean intrarenal pressure (IRP) during the procedure. The stone-free rate (SFR) was comparable between groups. The SENS group removed stones more efficiently, with shorter treatment time and less frequent use of the stone extractor. Lower IRP and shorter treatment time led to fewer postoperative complications.mPCNL with SENS results in lower IRP, faster stone removal, and reduced use of stone forceps while preserving SFR and safety.
