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.
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
In thoracic surgery, disposable instruments are significant drivers of cost. There is variation in disposable instrument use among surgeons. It was hypothesized that a "passive awareness" intervention (displaying a pricing list of disposable instruments in the operating theater) would decrease operative costs. A current price list of disposable instruments used in thoracoscopic lobectomy was displayed in the thoracic surgery operating theater. Consecutive patients who underwent thoracoscopic lobectomy 6 months prior to price list display (Period 1) and 6 months following price list display (Period 2) were analyzed. Descriptive statistics were used to describe case distribution and lobectomy costs. T test and linear regression were used to examine the impact of surgeon, lobe removed, and time period. Over the study period, 71 patients underwent thoracoscopic lobectomy (Period 1: n = 36, Period 2: n = 35). Median per-lobectomy disposables cost decreased from $2063.22 (Interquartile range [IQR] $788.49) in Period 1 to $1885.92 (IQR $552.26) in Period 2; p = 0.03. There was a significant reduction in the median number of "high cost disposables" between Periods 1 and 2 (5.5-5.0, respectively; p = 0.04). In multiple linear regression, there was a decrease in total per-lobectomy cost of $286.21 (p = 0.03) and a decrease in stapler cartridge cost of $266.89 (p = 0.03) when controlling for surgeon and lobe. There was a significant reduction in disposable instrument expenditure per thoracoscopic lobectomy following posting of instrument costs in the operating theater. These findings suggest that a simple passive awareness intervention is effective in influencing surgeon behavior to reduce disposable instrument costs.
