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

purposeTo determine whether there is an interaction between baseline serum chloride concentration and pH and treatment effects in Intensive Care Unit (ICU) patients receiving intravenous fluid therapy with balanced solution versus 0.9% sodium chloride (saline).

methodsA secondary analysis of a randomized controlled trial in which patients were divided into cohorts according to quartiles of baseline serum chloride concentration and pH. The primary outcome was day-90 mortality.

resultsFrom 4846 patients with outcome data available, 4823 with relevant baseline data were included in this analysis, with 1347, 1333, 993 and 1150 patients in the chloride quartiles of < 102, 102-106, 107-109 and > 109 mmol/L, respectively. Data were also analysed in pH quartiles of ≤ 7.27, 7.27-7.34, 7.34-7.39 and > 7.39. The risk-adjusted odds ratio (95% confidence interval [CI]) for day-90 mortality for patients assigned balanced solution compared to saline was 1.23 (0.95-1.58), 0.95 (0.73-1.25), 0.88 (0.64-1.21), and 0.76 (0.57-1.01) for lowest to highest chloride subgroups, respectively (P value for interaction = 0.10), and 0.89 (95% CI 0.69-1.15), 0.94 (0.70-1.27), 0.96 (0.67-1.38) and 1.15 (0.82-1.60) for pH quartiles from lowest to highest, respectively (P value for interaction = 0.63).

conclusionsThere were no significant differences in the treatment effect of balanced solutions compared to saline according to baseline serum chloride concentration or pH.
