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

purposeTo compare the preliminary postoperative outcomes of percutaneous endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of lumbar spondylolisthesis.

methodsSixty-two patients with single-segment lumbar spondylolisthesis received Endo-TLIF and MIS-TLIF were enrolled in present study. Perioperative parameters, including operation time, estimated blood loss (EBL), interoperative fluoroscopy time, ambulation time and operative complications were recorded, respectively. The results of clinical metrics such as the Visual Analog Scale (VAS) for back and leg pain, the Oswestry Disability Index (ODI) and the Japanese Orthopaedic Association (JOA) score were obtained, respectively. Postoperative fusion rates were assessed by clinical fusion and CT at 12-month after surgery.

resultsNo significant differences were found in the demographic data between the two groups. Compared with MIS-TLIF group, Endo-TLIF group had similar operative time, less intraoperative blood loss and shorter ambulation time but longer duration of X-ray radiation. The postoperative VAS scores of back pain, ODI and JOA score were significantly improved comparing with the preoperative scores in two groups, but the Endo-TLIF group showed more significant improvement in the early follow-up (P < 0.05, respectively). There were no significant differences in terms of the interbody fusion rate between the two groups. Meanwhile, no serious postoperative complications were observed in the study.

conclusionCompared with MIS-TLIF, Endo-TLIF technique showed relatively faster recovery and better outcomes in terms of early curative effect, especially in 6 months after operation. However, intraoperative repeated fluoroscopy could result in highly cumulative radiation and longer operation time.
