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

backgroundThese case reports focus on successful pain management with ultrasound-guided serratus posterior superior muscle (SPSM) block using 30 mL of 0.25% ropivacaine or physiological saline in three myofascial pain syndrome (MPS) patients presented with cervicoscapular pain. CASE PRESENTATION: The SPSM block was administered to three ambulatory patients (cases #1, #2, and #3) who presented with cervicoscapular pain. The SPSM block with 30 mL of 0.25% ropivacaine drastically decreased an NRS score and provided 2-3 weeks of pain relief in cases #1 and #2. On the contrary, the SPSM block with 30 mL of physiological saline also mildly decreased an NRS score and provided 3 weeks of pain relief in cases #1 and #3.

conclusionsThe SPSM block using 30 mL of 0.25% ropivacaine or physiological saline successfully decreased the NRS scores in three MPS patients. These findings suggest that the SPSM block may serve as a useful therapeutic option in MPS patients presenting with cervicoscapular pain.
