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

introductionTotal thyroidectomy (TT) is one of the most common procedures among general and endocrine surgeons worldwide. The conventional approach by neck incision is still the most frequently used, despite the growth of mini-invasive approaches. Controversies exist about the optimal learning curve for resident surgeons approaching this procedure. The aim of this study was to compare TT performed by experienced surgeons and residents in two academic hospitals, to define the correct shape of the specific learning curve.

methodsBetween January 2016 and December 2018 patients undergoing TT in two academic departments were prospectively enrolled. In each department patients were divided into four groups: a reference group (A), consisting of 50 consecutive patients operated on by a senior surgeon, and three other groups (B, C, D) of 50 patients each where thyroidectomy was carried out by three different general surgery residents in their last 3 years of residency, respectively. Data were analysed by CUSUM and KPSS tests in order to compare operative time (OT) and its stabilisation during the learning curve.

resultsData from CUSUM test reported that residents could perform TT with OT similar to the senior surgeon after approximately 25-30 procedures, while the KPSS test showed that residents became more stable after 30 procedures, with no increase in perioperative complications.

conclusionsThis prospective study shows how a specific training in thyroid surgery can be reliable thanks to experienced tutors, and confirmed that the effect of dedicated and programmed training may result in positive outcomes for patients requiring thyroidectomy.
