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

background5-Aminolevulinic acid (5-ALA) is useful as a photodynamic agent, but its use commonly leads to hypotension. Although avoiding a mean arterial pressure (MAP) < 60 mmHg is important, the incidence of MAP < 60 mmHg when using 5-ALA is unclear. Therefore, we conducted a retrospective study to assess the incidence of post-induction hypotension and identified risk factors of this phenomenon.

methodsOne-hundred and seventy-two consecutive patients who underwent transurethral resection of the bladder tumor or craniotomy with the use of 5-ALA were enrolled. The primary outcome was the incidence of post-induction hypotension, defined as MAP < 60 mmHg during the first 1 h after anesthesia induction. We divided participants into the normal blood pressure group (group N) and the hypotension group (group L).

resultsThe incidence of post-induction hypotension was 70% (group L = 121, group N = 51). Multivariate analysis revealed that female sex was an independent factor of post-induction hypotension (odds ratio [OR] 3.95; 95% confidence interval [CI] 1.21-12.97; p = 0.02). Systolic blood pressure < 100 mmHg before anesthesia induction and general anesthesia were also identified as significant independent factors (OR 13.30; 95% CI 1.17-151.0; p = 0.04 and OR 25.84; 95% CI 9.80-68.49; p < 0.001, respectively).

conclusionsThe incidence of post-induction hypotension was 70% in patients using 5-ALA. Female sex, systolic blood pressure < 100 mmHg before anesthesia induction, and general anesthesia might be independent factors of post-induction hypotension when using 5-ALA.
