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

objectiveThe aim of this study was to analyze the influence of epidural catheters on the incidence of intravascular injection and to identify possible predictors of intravascular injection in patients undergoing a caudal block using fluoroscopy.

methodsA total of 154 patients scheduled to receive a caudal block were randomized into group N (those without epidural catheter) or group C (those with epidural catheter). Demographic and clinical data were recorded and analyzed.

resultsThe incidence of intravascular injection was 15.6% in group N, 6.5% in group C, and 11.0% overall, without statistical differences between the two groups (P = 0.105). Univariate analysis revealed that blood at hub (P = 0.047) and positive aspiration test (P = 0.045) were more frequently observed in group N than in group C. Quality of analgesia was significantly higher in group C than in group N (P = 0.029). Multivariate analysis identified older age (P = 0.024), blood at hub (P = 0.003), and positive aspiration test (P = 0.001) as predictors of intravascular injection.

conclusionsIn this study, while the incidence of intravascular injection during caudal blocks was less frequent with epidural catheter use, it was not statistically significant. However, a caudal block using an epidural catheter provided a lower incidence of blood at hub, fewer positive aspiration tests, and superiority in pain improvement.
