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
objectiveTo evaluate the efficacy and safety of totally extraperitoneal endoscopic hernioplasty (TEP) compared to the Lichtenstein hernioplasty in adult patients with uncomplicated inguinal hernia.
methodsA systematic review and meta-analysis were conducted following PRISMA guidelines. We included 27 randomized controlled trials (RCTs) identified through comprehensive searches in Embase, Web of Science, PubMed, Scopus, and Cochrane Library. Studies comparing TEP and Lichtenstein techniques in adult patients with uncomplicated inguinal hernias were selected. Primary outcomes included hernia recurrence and chronic postoperative pain. Secondary outcomes assessed were surgical wound infection, seroma, hematoma, scrotal edema, operative time, hospital stay (in hours and days), and time to return to daily activities.
resultsA total of 27 RCTs with 7,658 patients were analyzed. No significant difference was found in hernia recurrence between TEP and Lichtenstein (RR 1.03; 95% CI [0.62-1.72]; p = 0.90). However, TEP significantly reduced the risk of chronic postoperative pain by 62% (RR 0.38; 95% CI [0.28-0.51]; p < 0.00001), surgical wound infection by 52% (RR 0.48; 95% CI [0.31-0.75]; p = 0.001), and hematoma formation by 37% (RR 0.63; 95% CI [0.41-0.97]; p = 0.04). No significant differences were found for seroma formation (RR 1.17; 95% CI [0.98-1.40]; p = 0.08) or scrotal edema (RR 0.62; 95% CI [0.35-1.10]; p = 0.10). Operative time showed no significant difference (MD 7.78 min; 95% CI [-2.77-18.33]; p = 0.15). Regarding hospital stay, TEP reduced the duration in days (MD -0.83; 95% CI [-1.24 to -0.41]; p < 0.0001), while no difference was observed when measured in hours (MD 0.01; 95% CI [-0.29-0.31]; p = 0.95). Furthermore, TEP was associated with a faster return to daily activities by approximately 5 days (MD -4.74; 95% CI [-6.78 to -2.70]; p < 0.00001).
conclusionThe TEP technique is more effective in terms of chronic pain, risk of surgical wound infection, and reduction of hematoma formation than the Lichtenstein technique.
