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

Study design: prospective, observational. Background: Wound drainage's indwelling duration and general use are the centre of ongoing discussion. The aim of our prospective observational study was to evaluate the total drainage volume postoperatively and its course after lumbar interbody fusion surgeries to define an ideal point in time for drainage removal. Methods: We included all patients who underwent monosegmental lumbar interbody fusion via transforaminal or posterior lumbar interbody fusion (TLIF/PLIF). After application of the exclusion criteria, 27 patients were included in our study. Drainage volume was measured three times a day and at the time of drain removal. Results: The PLIF group reached higher total drainage volume (337.14 ml) than the TLIF group (215.5 ml) (p = 0.047. Drainage volume's plateau was reached after 33.0 h (±1.8 h) in the TLIF group and 25.3 h (±1.7 h) in the PLIF group following surgery. Conclusions: Our study shows, that drainage volume did not increase significantly after the evening of the first postoperative day at latest. This was on average 33.0 h after surgery. Therefore, extraction of the drainage tube hereafter can be assumed to be safe.
