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

backgroundSince 2013 surgical units in Sweden have reported procedures to the national Swedish Perioperative Register (SPOR). More than four million cases have been documented. Data consist of patient ID, type of surgery, diagnoses, time stamps during the perioperative process (from the decision to operate to the time of discharge from the postoperative recovery area) and quality measures. This article aims to describe SPOR and validate data mapping. Also, we wished to illustrate the utility of the SPOR in assessing variations in national surgical capacity during the COVID-19 pandemia years 2020-2021.

methodsAfter a detailed description of SPOR, we report on the validation of data performed by comparing data from local databases with data stored in the central SPOR database, assessing missing values and accuracy. Effects of the pandemic on surgical capacity were described by developing an index, based on the number of performed surgical procedures per week during four production weeks in January 2020. Subsequent weeks were then compared with this baseline.

resultsThe validation effort demonstrated nearly 100% data accuracy for the number and type of surgical procedures between local and central data. Missing data was a problem for some parameters. The number of performed surgical procedures decreased dramatically from week 11 in 2020 compared with normal production on a national basis, mainly impairing elective surgery. DISCUSSION: Data validation revealed good agreement between local and central databases. The changes in national surgical capacity during the pandemic were illustrated by an index based on the reported surgical production.
