Ultrasound-guided intercostal nerve blocks for acute zoster pain: a retrospective, propensity score-matched, non-inferiority study.
Article in Journal of ultrasonography, 2025. 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
Aim: To assess whether ultrasound (US)-guided intercostal nerve blocks (ICNBs) provide non-inferior efficacy in the management of acute zoster pain (ZAP) and potential prophylaxis for post-herpetic neuralgia as compared to conventional thoracic paravertebral blocks (TPVBs). Material and methods: A total of 192 patients with ZAP were reviewed. Their records were stratified into two cohorts: those who underwent US-guided TPVBs (TPVB cohort) and those who received US-guided ICNBs (ICNB cohort). The ICNB cohort was matched using a propensity score method in a 1:1 ratio. The primary endpoint was non-inferiority of Results: Mean score of HZ-BOI Conclusions: US-guided ICNBs were non-inferior to TPVBs in alleviating ZAP and preventing post-herpetic neuralgia, while also demonstrating a favorable safety profile. These findings suggest that the ICNB technique might be a promising alternative for managing ZAP.
