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

backgroundThis pilot case series evaluated the feasibility and effectiveness of using endoscopic radiofrequency ablation (RFA) of the articular branch of the anterior obturator nerve under endoscopic and fluoroscopic guidance for controlling pain in patients with osteonecrosis of the femoral head (ONFH).

methodsData on 11 consecutive patients were collected with ONFH underwent endoscopic RFA of the anterior obturator nerve. Electromyography (EMG) examination was performed preoperatively and postoperatively. Visual Analogue Scale (VAS) scores, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, and analgesic usage were recorded preoperatively, on the day of surgery, and at 1, 3, and 6 months postoperatively.

resultsThe study included 5 males and 6 females, aged 45 to 91 years (mean age: 70.4 ± 14.6 years), with an average BMI of 29.5. All patients completed a minimum of 6 months of follow-up. Postoperative EMG showed no muscle damage. VAS and WOMAC scores demonstrated significant improvement, with reduced pain, stiffness, and improved hip function. Oral analgesic use also decreased.

conclusionEndoscopic RFA of the anterior obturator nerve effectively reduces pain and improves function in ONFH patients over 6 months. Further studies are needed to confirm long-term outcomes.
