The Incidence of Negative Laparoscopy for Pelvic Pain Stratified by Level of Training and Location of Service Provision.

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
aimSystematic reduction of negative laparoscopy for pelvic pain is crucial to reducing surgical morbidity, improving diagnostic accuracy and minimising cost. This study aims to determine the incidence and consider the underlying causes of negative laparoscopy in women presenting with pelvic pain.
methodsA 5-year, retrospective cohort study was undertaken for women undergoing laparoscopy for pelvic pain. Patient selection was from an Australian tertiary public hospital with both non-fellowship trained gynaecologists and an Australasian Gynaecological Endoscopic Surgery (AGES) accredited training programme (fellowship trained) as well as one private clinic comprising two fellowship trained gynaecologists. Data was collected from the medical records. A 'negative' laparoscopy was defined either visually or by vision and negative biopsy on histology. The rate of negative laparoscopy in the public and private sector was compared using an odds ratio.
resultsOf 1309 women, 174 (13%) had a negative laparoscopy. The negative laparoscopy rate was significantly higher amongst non-fellowship trained gynaecologists compared to those with fellowship training (OR = 2.48; 95% CI: 1.76-3.43, p < 0.05). Visually negative laparoscopy was made in 48/174 (28%) of cases, all from the public sector, with 41/48 (85%) of laparoscopies without biopsy performed by non-fellowship trained gynaecologists. A 56% discordance between intraoperative visualisation and histopathological findings was identified.
conclusionOverall, negative laparoscopy rates are low compared to previously reported data. The discrepancy between the healthcare sectors likely relates to patient factors, surgical training, and clinician bias. Peritoneal biopsy for symptomatic patients undergoing laparoscopy should be considered due to the potential to miss superficial disease.
