Ultrasound-guided anteroposterior percutaneous catheter drainage for the treatment of psoas abscess: A case series.
Article in Science progress. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Psoas abscess (PA) is a rare but potentially life-threatening condition that requires prompt intervention. The role of ultrasound-guided percutaneous catheter drainage (US-PCD) via the anterior-posterior (AP) approach warrants further evaluation. This case series retrospectively analyzed 10 patients with PA who underwent US-guided AP-PCD at Beijing Friendship Hospital. Data collected included procedure duration, pre- and postoperative clinical examinations, inflammatory markers, and imaging findings. Technical success was achieved in all cases (median procedure time: 18.5 minutes). Postprocedural Visual Analog Scale (VAS) pain scores decreased within 24 hours. By postoperative day 3, eight patients had normalized body temperature and white blood cell (WBC) counts. Median C-reactive protein (CRP) levels decreased from 151.3 mg/L (range: 58.0-269.4) preoperatively to 49.5 mg/L (range:38.7-186.1) postoperatively. During a follow-up period of 1-6 months, six patients achieved clinical success without further intervention, two required surgical debridement, and two died. This case series demonstrates that US-guided AP-PCD represents a feasible and safe minimally invasive option for selected patients with PA, offering the advantages of real-time guidance and no radiation exposure. However, given the modest success rate (60%) and etiological heterogeneity of this cohort, larger prospective studies are needed to validate its clinical role.
