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

backgroundThe objective of this study was to evaluate the significance of preoperative heart rate variability (HRV) as a surrogate marker for vagus nerve activity in predicting the incidence of postoperative pneumonia (POP) and lung function recovery in patients undergoing lung cancer surgery.

methodA prospective observational study was conducted at a single center. Patients were categorized into two groups: the POP group, which included those who developed pneumonia post-surgery, and the non-POP group, comprising patients who did not experience POP.

resultsA total of 257 subjects met the inclusion criteria and were ultimately included in the study. 33 patients presented POP, accounting for 12.8% (33/257) of the patients. Logistic regression revealed that preRMSSD (OR: 0.812, 95%CI: 0.720-0.912, P = 0.001) and preHFP (OR: 0.990, 95%CI: 0.983-0.996, P = 0.002) were the independent factors for POP; receiver operating characteristic curve (ROC) analysis for predicting the occurrence of the POP revealed that the combination of BMI, preHFP and preRMSSD showed the positive diagnostic accuracy (AUC: 0.867, P < 0.001). A logistic regression analysis showed that HRV indicators including preRMSSD (OR: 0.937, 95%CI: 0.892-0.985, P = 0.010) and preHFP (OR: 0.995, 95%CI: 0.992-0.998, P = 0.001) were independent factors for well-recovery in FEV1% within postoperative 30 days. Similar results can be found in well-recovery in FVC% or DLCO%.

conclusionThese findings provided compelling evidence supporting the utility of HRV indicators in predicting both POP and postoperative lung function recovery among surgical lung cancer patients.
