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

backgroundChronic post-surgical pain (CPSP) is a prevalent complication following video-assisted thoracic surgery (VATS), significantly affecting long-term patient outcomes. This study aimed to evaluate the influence of uniport versus multiport VATS on the incidence of CPSP and postoperative recovery at six months.

methodsPatients were stratified into uniport and multiport VATS groups, with propensity score matching (PSM). The primary endpoint was the incidence of CPSP at six months. The secondary endpoints comprise the short-term recovery outcomes within 30 days postoperatively, the quality of life at six months and group-based trajectory modeling to characterize pain trajectories over six months.

resultsAfter PSM, 222 patients (111 per group) were included in the final analysis. A significant difference in postoperative pain intensity {3(1.8-4) vs 4(3-5), P = 0.007} was observed on postoperative day 3 (POD3). However, no significant difference in CPSP incidence at six months was detected between the uniport and multiport VATS groups. Multivariate logistic regression analysis of the entire cohort identified a high pain score on POD3 as an independent risk factor for CPSP development. Pain trajectory analysis revealed three distinct postoperative pain patterns over the six-month period. Patients in the high pain trajectory required more remedial analgesia and were more likely to develop CPSP.

conclusionsUniport VATS was not associated with a lower incidence of CPSP compared to multiport VATS at six months postoperatively. A high pain score on POD3 emerged as a significant predictor of CPSP.
