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

purposeRecurrent lumbar disc herniation (RLDH) is an important cause of morbidity and healthcare costs. The goal of this investigation is to assess surgical outcomes and their predictors in patients who underwent revision discectomy for RLDH, with a minimum follow-up of ten years, to shed light on the best treatment to offer to these patients.

methodsPatients who underwent revision discectomy to treat RLDH between 2004 and 2011 in our Department were enrolled. Demographic, clinical, and surgical data were collected. The need of third intervention for RLDH was the primary outcome. Patient's satisfaction, Core Outcome Measures Index, Oswestry Disability Index, and EuroQoL-5D scores were also evaluated.

resultsThis study includes 55 patients, with a mean follow-up time of 144 months [112-199]. In this period, a third intervention was needed in 30.9% (n = 17) of patients. Most recurrences took place in the first 2 years after the second surgery (58.8%, n = 10) and the risk of needing a third surgery decreased over time. After 5 years, the probability of not having surgery for recurrence was 71% [CI 95%: 60-84%], with a tendency to stabilize after that. An interval between the first discectomy and the surgery for recurrence shorter than 7.6 months was identified as a predictor for a second recurrence.

conclusionThe risk of needing a third surgery seems to stabilize after five years. Patients with an early recurrence after the first discectomy seem to have a higher risk of a new recurrence, so an arthrodesis might be worth considering.
