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

backgroundParavertebral block (PVB) conducted by epidural catheter is a prevalent pain management for patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy. The aim of this study was to assess the efficacy and safety of paravertebral block with a modified PVB (MPVB) catheter under surgeon's direct vision after video-assisted thoracoscopic lobectomy.

methodsThree hundred fifty-six patients undergoing VATS lobectomy were retrospectively reviewed and divided into two groups consecutively according to the catheter applied in PVB procedure (PVB group and MPVB group). In the MPVB group, a modified catheter with a flexible forepart and more apertures distributing along the forepart than the conventional epidural catheter was introduced. An infusion pump containing of 150 mL mixture was connected to the catheter to provide sustained regional analgesia. Intramuscular dezocine 10 mg was administered as a rescue medication when necessary. Postoperative pain management effect was assessed by visual analog scale (VAS) at rest and on coughing. Spirometry values and blood gas analysis were monitored and recorded for the first 3 postoperative days (PODs). Analgesia-related adverse events, characteristics of PVB procedure and postoperative major complication were also compared between the two groups.

resultsThere were 172 patients who received PVB with conventional epidural catheter in the PVB group, and 184 patients were performed PVB with modified paravertebral catheter in the MPVB group. Significantly lower pain score at rest was found in MPVB group at 24 h postoperatively (P=0.006). The pain score on coughing in MPVB group was significantly lower than that in PVB group at 12 and 24 h postoperatively (P=0.037 and P<0.001, respectively). Patients needing for rescue medication was significantly lower in the MPVB group (P=0.028). The incidence of pleural perforation was lower in the MPVB group (P=0.020). Postoperative spirometry values revealed comparable pulmonary function between the two groups, and arterial blood gas analysis showed a normal range of pH and PaCO2 in both groups. There was no significant difference of analgesia-related adverse events as well as major complications between the two groups.

conclusionsPVB with modified catheter under surgeon's direct vision was effective and safe after video-assisted thoracoscopic lobectomy.
