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

backgroundThe short-term results of the TULIP trial comparing transinguinal preperitoneal (TIPP) inguinal hernia repair with the Lichtenstein method have been reported with follow-up of 1 year. After TIPP repair, fewer patients had chronic postoperative inguinal pain (CPIP); they had better health status and lower costs. The present study reports the long-term outcomes of this trial.

methodsAll surviving patients initially randomized in the TULIP trial were contacted. Patients were interviewed by telephone and sent a questionnaire. Those reporting any complaints were invited for outpatient review. Chronic pain, hernia recurrence and reoperation were documented, along with any sensory change or disturbance of sexual activity.

resultsOf 302 patients initially randomized, 251 (83·1 per cent) were included in the analysis (119 TIPP, 132 Lichtenstein), with a median follow-up of 85 (range 74-117) months. Of 25 patients with chronic postoperative inguinal pain after 1 year, only one, who underwent Lichtenstein repair, still had groin pain at long-term follow-up. The overall hernia recurrence rate was 2·8 per cent (7 patients), with no difference between the groups.

conclusionBoth TIPP and Lichtenstein hernia repairs are durable. Patients with chronic postoperative inguinal pain after 1 year can be reassured that the groin pain tends to fade over time.
