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

aimTo assess the validity and cover rate of the Swedish hernia register. MATERIAL AND

methodsSince the start of the Swedish Hernia register an annual review of randomly selected hospitals has been carried out, and since 2013 in a more standardized form to allow a systematic data collection and evaluation. 10% of all clinics were randomly selected each year in a specific region of Sweden, ensuring a systematic validation of all regions from north to south. Data from 2013 to 2018 were analyzed regarding data quality and from 2014 to 2018 regarding cover rate. All operations registered at the validated clinics were compared with the Swedish Hernia Register to assess cover rate. Fifty operations were randomly selected at each clinic and data in the Swedish Hernia register were compared with the medical records to evaluate data quality.

resultsFifty-five clinics was evaluated and a total of 73,764 variables were compared with the medical records. Cover rate between 2014 and 2018 was 97%. The proportion of correct variables was 98% between 2013 and 2018. Most frequent errors were ASA score, date at which the patient was put on the waiting list and postoperative complications.

conclusionThis unique validation of a national hernia register shows a high cover rate and good quality of data. Efforts to maintain and improve national registers are of great importance. Research with data from the Swedish hernia register should be evaluated on the basis of the results presented in this study.
