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

purposeSmall femoral hernias may be difficult to diagnose by physical examination and are sometimes identified unexpectedly by laparoscopy. The aim of this study was to examine the incidence of unsuspected femoral hernia discovered during laparoscopic inguinal hernia repair in two well-defined patient groups.

methodsPatients undergoing laparoscopic transabdominal preperitoneal inguinal hernia repair from April 2000 until December 2009 (n = 561) were prospectively registered including data on previous hernia operations and identified type of hernia during surgery. We included patients whose preoperative diagnosis was either bilateral primary inguinal hernia (Primary Group) or recurrent inguinal hernia (Recurrent Group).

resultsFour hundred and sixty-one (82.2 %) patients were included in the study, of whom 211 (45.8 %) was in the Primary Group and 250 (54.2 %) in the Recurrent Group. The incidence of unsuspected femoral hernia in the Recurrent Group [23/250, 9.2 % (95 % CI 5.9-13.5 %)] was significantly higher than in the Primary Group [8/211, 3.8 % (95 % CI 1.7-7.3 %)], p = 0.02. Furthermore, 38.1 % of women operated on for a recurrent inguinal hernia, presented with an unsuspected femoral hernia at surgery as opposed to 6.6 % of the men, p = 0.003.

conclusionUnsuspected femoral hernias are more prevalent in patients with recurrent hernia than in patients with primary hernia in the inguinal region. Femoral hernias may be unrecognized at the primary inguinal hernia operation, or the previous inguinal hernia operation may facilitate the formation of a femoral hernia. Unsuspected femoral hernias are especially frequent in women with recurrent inguinal hernia. In women with a groin hernia, a femoral hernia should always be excluded by laparoscopy or by open exploration of the preperitoneal space.
