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

Background and aim: While oral Chinese herbal medicine (OCHM) is frequently used for cancer pain (CP), its combined effects with opioids remain unclear. This study aims to evaluate the efficacy and safety of OCHM combined with opioids in patients with moderate to severe CP. Experimental procedure: We systematically searched five Chinese and English databases up to December 30th, 2024, for randomized controlled trials comparing OCHM plus opioids versus opioids alone. Primary outcomes were pain relief and pain intensity. Secondary outcomes included onset and duration of pain relief, Karnofsky Performance Status (KPS) score, and adverse events. Results: Meta-analysis of 18 trials revealed that OCHM plus opioids had a lower pain intensity (standardized mean difference [SMD] = -1.70; 95 % CI = -2.31 to -1.08; Conclusion: OCHM plus opioids improved pain relief, enhanced the quality of life, reduced opioid-related adverse events in patients with moderate to severe CP compared to opioids alone.
