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

introductionWe hypothesise that distinct postoperative pain trajectories are significantly associated with postoperative recovery outcomes. To test this, we will systematically investigate the dynamic trajectories of postoperative pain, identify influencing factors and explore the relationship between pain trajectory categories and recovery within 1 month postoperatively. METHODS AND ANALYSIS: We plan to enrol 1000 day surgery patients. The primary outcome measure will be the recovery status at 1 month postoperatively, assessed using the Recovery Quality of Life Scale-15. The secondary outcome measures will be the patients' subjective recovery ratings, satisfaction scores and pain interference with daily life scores. To capture pain progression, assessments will be conducted at four time points (days 1, 3, 7 and 30) using the Brief Pain Inventory. Latent class growth analysis will identify distinct pain trajectory classes, and their association with postoperative recovery will be examined. Generalised linear mixed models and least absolute shrinkage and selection operator regression will be used to identify risk factors for high-risk pain trajectories. ETHICS AND DISSEMINATION: This study has been approved by the Sichuan Provincial Medical Ethics Committee (ethical review No. 749, 2024). Findings will be disseminated to participants, funders, the research community and the public to ensure transparency and accessibility. TRIAL REGISTRATION NUMBER: ChiCTR2500095991.
