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.

2 · The registry

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 determine if the presence or absence of sonographic sliding sign preoperatively is a good predictor of the presence and type of intra-abdominal adhesions; and to determine the time taken to demonstrate this sign.

designA prospective, observational, triple-blind study using tests of diagnostic accuracy.

settingSingle-centre tertiary health institution in north-east Nigeria.

participants67 women in the third trimester scheduled for repeat elective caesarean sections (CS) had transabdominal sonography to determine the absence or presence and degree of sliding sign. The time taken to make these decisions were noted. Surgeons blinded to the ultrasound findings graded adhesions intraoperatively and comparison between sonographic and intraoperative findings made. Women who were scheduled for emergency CS were excluded.

main outcome measuresAccuracy of preoperative ultrasound to determine no/mild, moderate and severe adhesions. Secondary outcomes were interobserver correlations and time taken to determine sliding.

resultsWhen classified as adhesion and no adhesion, the sliding sign demonstrated a sensitivity of 100.00% (CI

conclusionThis study supports the role of transabdominal sliding sign in preoperative prediction of intra-abdominal adhesions in women with previous CS without significant increase in sonography duration. This information can encourage planning for CS by ensuring that surgeons of appropriate seniority are deployed to undertake anticipated complex operations.
