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

BACKGROUND AND

aimFactors influencing reading time and detection of lesions include the view mode (VM) and frame rate (FR) applied during reading of small bowel capsule endoscopy images. The aims of this study were to examine the impact of VM and FR on reading time and lesion detection using a standardized, single-type lesion model.

methodsA selected video clip containing a known number of positive images (n = 60) of small bowel angioectasias was read using nine different combinations of VM and FR (VM1, VM2, and VM4 × FR10, FR15, and FR25) in randomized order by six capsule endoscopists. Readers were asked to count all positive images of angioectasias (maximum number of positive images, MPIs) seen during reading. The main outcome measurements were effect of VM and FR on reading time and lesion detection.

resultsMean MPIs for all VM2 and VM4 were 36 (60 %) and 38 (64 %). They were significantly higher than VM1 of 24 (40 %) (P = 0.011, 0.008). A statistical difference was found when the total MPIs at FR10 were compared to FR15 (P = 0.008) and to FR25 (P < 0.001).

conclusionsBoth VM and FR significantly influence lesion detection during capsule endoscopy reading.
