Laparoscopic-assisted transversus abdominis plane block as an effective analgesic in total extraperitoneal inguinal hernia repair: a double-blind, randomized controlled trial.
Trial report in Hernia : the journal of hernias and abdominal wall surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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
purposeLaparoscopic inguinal hernia repair has facilitated early mobilization. Management of post-operative pain is paramount in these day case procedures. The aim of this study was to compare laparoscopic-assisted transversus abdominis plane (TAP) block with periportal local anaesthetic infiltration in managing post-operative pain.
methodsA double-blind, randomized controlled trial was conducted with patients undergoing elective laparoscopic inguinal hernia repair (January 2016-October 2017). The intervention group received laparoscopic-assisted TAP block with 30 ml 0.25% Bupivacaine. The control group received 15ml of 0.5% Bupivacaine at the periportal sites. Primary outcome measure was assessment of post-operative pain scores using numerical rating on visual analogue scale (VAS) at rest and on coughing at 3 h. Efficacy of TAP block was assessed as reduction in mean pain scores in the order of 2 points using the VAS.
results60 (57 males and 3 females) were enrolled; 30 patients were randomized to each group. Patient demographics, anaesthetic and surgical times were similar in both groups. Mean pain scores were significantly reduced in the intervention group at 3 (3.1 vs 1.1 p < 0.001) and 6 h (4.1 vs 1.7 p < 0.001) at rest and on coughing at 3 (4.8 vs 2.1 p < 0.001) and 6 h (5.4 vs 3.0 p < 0.001). Patient satisfaction was higher (8.0 vs 6.8 p < 0.001) and rescue analgesic requirements (169.4vs 71.3 p < 0.001) lower in the intervention group.
conclusionsThis analysis has demonstrated the therapeutic benefit of laparoscopic-assisted TAP block in initial post-operative pain management for patients undergoing elective laparoscopic inguinal hernia repair.
