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

objectiveWe recently reported in a multi-institutional, randomized study of laparoscopic paraesophageal hernia repair (LPEHR) that the anatomic recurrence rate at a median of approximately 5 years was >50%. This study focuses exclusively on the symptomatic response to LPEHR and its relationship with the development of a recurrent hernia.

methodsDuring 2002 to 2005, 108 patients underwent LPHER with or without biologic mesh. A standardized symptom severity questionnaire, SF-36 health survey, and upper gastrointestinal series were performed at baseline, 6 months, and during 2008-2009.

resultsOf 108 patients, 72 (average age of 68 ± 10 years) underwent clinical assessment, and 60 of them also had radiologic studies at a median follow-up of 58 (40-78) months. Radiographic recurrence (≥ 20 mm) was 14% at 6 months and 57% at the time of follow-up, and the average recurrence size was 40 ± 10 mm. All symptoms were significantly improved at long-term follow-up and, with the exception of heartburn, were unaffected by the presence or size of the recurrence. Two patients (3%) with recurrent symptoms related to their hernia underwent reoperation.

conclusionDespite frequent radiologic recurrences after LPEHR, symptoms remain well controlled, patient satisfaction is high, and the need for reoperation is low.
