Polytetrafluoroethylene versus polypropylene mesh during laparoscopic totally extraperitoneal (TEP) repair of inguinal hernia: short- and long-term results of a double-blind clinical randomized controlled trial.
Trial report in Hernia : the journal of hernias and abdominal wall surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02023203 (Prospective Randomized Clinical Trial Comparing Microporous Polypropylene Mesh and Flexible Macroporous Polytetrafluoroethylene Mesh in Totally Extraperitoneal Laparoscopic Inguinal Hernia Repair), which is not on this map. Cited by 9 papers, 1 of them a synthesis 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.

Abstract
purposeAim of the study is to compare macroporous (> 1 mm
methodsFifty-two patients with bilateral hernia were enrolled in this double-blind randomized controlled trial (NCT02023203). Each hernia, in the same patient, was randomized to implant LP-PTFE or SP-PPL mesh during totally extraperitoneal laparoscopic hernia repair. Patients were followed at 7 days, 1, 3, 6, 12 and 60 months after surgery. Visual analog scale (VAS) score was employed to evaluate the outcomes. Student's t test was used in case of normally distributed continuous variables, while the nonparametric Mann-Whitney U test was used in case of not normally distributed variables. Chi square test was used for analysis of categorical variables.
resultsMedian VAS discomfort score with SP-PPL was significantly higher than LP-PTFE at 1 and 3 months after surgery (p = 0.003 in both cases). LP-PTFE showed significantly lower median score than SP-PPL at 7 days after surgery (p = 0.025) regarding pain at movement. Testicular pain was lower in case of LP-PTFE than SP-PPL at 7 days, 1 and 3 months after surgery (p = 0.005, p = 0.004 and p = 0.004, respectively). LP-PTFE was significantly more difficult to handle (p = 0.001). At 60 months, one recurrence was observed in the LP-PTFE group (p = 1.0000).
conclusionsLP-PTFE has less postoperative discomfort and pain up to 3 months after surgery, without differences after that period, although it shows more difficulty in handling and recurrences occur even if not statistically significant.
