One year results of a randomised controlled multi-centre study comparing Prolene and Vypro II-mesh in Lichtenstein hernioplasty.
Trial report in Hernia : the journal of hernias and abdominal wall surgery, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 5 of them syntheses that pooled 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.
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
A standard polypropylene mesh used in Lichtenstein's operation induces a strong foreign tissue reaction with potential harmful effects. A mesh with less polypropylene could possibly be beneficial. Six hundred men with primary unilateral inguinal hernias were randomised to Lichtenstein's operation using a Prolene- or Vypro II-mesh in six centres. The patients were blinded to which mesh they received. A validated questionnaire assessing recurrence and pain along with SF-36 Health Survey was sent after 1 year to all patients and a selected group was clinically examined. Of the 591 operated patients, 526 (89.0%) returned the questionnaire. 188 patients had some complaints or sensations of which 111 patients were clinically examined. The mean follow-up time was 13.6 (SD. 4.0) months. The incidence of hernia recurrence (four vs. four patients) and neuralgia (three vs. four patients) did not differ between Prolene and Vypro II-groups, respectively. One Vypro II-patient was re-operated due to neuralgia. There was no difference in the SF-36 scores. The results of Lichtenstein's operation with either Prolene or Vypro II do not seem to differ significantly.
