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

purposeBeginners usually need increased punctures and dozens of fluoroscopy in learning transforamimal percutaneous endoscopic lumbar discectomy (tPELD). Navigator-assisted spinal surgery (NASS) is a novel technique that could induce a definite trajectory. The retrospective study aimed to investigate the impact of a definite trajectory on the learning curve of tPELD.

methodsA total of 120 patients with symptomatic lumbar disc herniation who received tPELD between 2012 and 2014. Patients receiving tPELD with NASS technique by one surgeon were regarded as group A, and those receiving conventional methods by another surgeon were regarded as group B. Each group was divided into three subgroups (case 1-20, case 21-40, case 41-60).

resultsThe fluoroscopy times were 22.62 ± 3.80 in group A and 34.32 ± 4.78 in group B (P < 0.001). The pre-operative location time was 3.56 ± 0.60 minutes in group A and 5.49 ± 1.48 minutes in group B (P < 0.001). The puncture-channel time was 21.85 ± 4.31 minutes in group A and 34.20 ± 8.88 minutes in group B (P < 0.001). The operation time was 84.62 ± 9.20 minutes in group A and 101.97 ± 14.92 minutes in group B (P < 0.001), and the learning curve of tPELD in group A was steeper than that in group B. No significant differences were detected in patient-reported outcomes, hospital stay, patient satisfaction, and complication rate between the two groups (p > 0.05).

conclusionsDefinite trajectory significantly reduced the operation time, preoperative location time, puncture-channel time, and fluoroscopy times of tPELD by beginners, and thus reshaped the learning curve of tPELD and minimized the radiation exposure.
