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

purposeEmergency laparotomy (EL) carries a high risk of morbidity and mortality, that is greater among older patients. Sarcopenia refers to an age- or pathology-associated muscle loss and has been demonstrated to correlate with poorer outcomes in several surgical conditions. This study assessed the impact of sarcopenia on morbidity and mortality in elderly patients undergoing EL.

methodsPatients aged ≥ 65 years-old undergoing EL between May 2012-June 2017 with a pre-operative abdominal computerised tomography (CT) scan at Middlemore Hospital (New Zealand) were included. Psoas and Skeletal Muscle Index (PMI and SMI) were calculated from abdominal CT measurements after standardisation based on height. Validated cut-offs for sarcopenia were used. Frailty was estimated using the 11-point modified frailty index (mFI). The primary outcome was 30-day, 1-year, and 4-year post-operative mortality. Secondary outcomes included correlations between mFI and sarcopenic measures, unplanned readmissions, and post-operative complications.

resultsA total of 167 patients (84 sarcopenic; 83 non-sarcopenic) were included. Sarcopenic and non-sarcopenic patients had similar 30-day (14.2 vs. 12.0%; p = 0.84), 1-year (23.8 vs. 25.3%; p = 0.96), and 4-year (39.3 vs. 47.0%; p = 0.40) mortality rates following an EL. Survivors had a higher mean PMI at 1-year (p = 0.0078) and 4-year (p = 0.013) but not 30-day (p = 0.40) follow-up. Sarcopenia performed poorly in discriminating between 30-day (AUC 0.51) and 1-year (AUC 0.53) mortality. The mFI did not correlate with PMI (p = 0.85) nor SMI (p = 0.18). Rates of readmissions and post-operative complications did not differ between sarcopenic and non-sarcopenic cohorts.

conclusionSarcopenia does not provide useful short-term prognostic information in elderly EL patients.
