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.

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

purposeTo compare resected cone mass and resection margin status when performing Large Loop Excision of the Transformation Zone (LLETZ) using video colposcopy (LLETZ-VC) versus a headlight (LLETZ-HL) in women with cervical dysplasia.

methodsProspective, randomised trial (monocentric) at a specialised cervical dysplasia unit in a University Hospital. Women with a biopsy-proven CIN2 + or persisting CIN1 or diagnostic LLETZ were recruited and randomised. LLETZ was performed either under video colposcopic vision or using a standard surgical headlight. The primary endpoint was resected cone mass. Secondary endpoints were the rate of involved margins, fragmentation of the specimen, procedure time, time to complete haemostasis (TCH), blood loss, pain, intra- and postoperative complications, and surgeon preference.

resultsLLETZ-VC and LLETZ-HL (109 women each) had comparable cone masses (1.57 [0.98-2.37] vs. 1.67 [1.15-2.46] grams; P = 0.454). TCH was significantly shorter in the LLETZ-VC arm (60 [41-95.2] vs. 90 [47.2-130.2] seconds; P = 0.008). There was no statistically significant difference in involved resection margins (6/87 [6.5%] vs. 16/101 [13.7%], P = 0.068) and postoperative complications (13/82 [13.7%] vs. 22/72 [23.4%], P = 0.085). Patient-reported outcomes favoured LLETZ-VC with a lower use of analgesics (6/80 [7.0%] vs. 17/87 [16.3%]; P = 0.049). However, LLETZ-VC was more difficult to perform with significantly lower ratings for handling (7 [5-9] vs. 9 [8-10]; P < 0.001) and general satisfaction (7.5 [5-9] vs. 10 [8-10]; P < 0.001).

conclusionIntraoperative video colposcopy for LLETZ has minimal benefits at the cost of surgeons' satisfaction. CLINICAL
