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

backgroundAlthough the risk calculator of the National Clinical Database (RC-NCD) has been widely used to predict the occurrence of mortality and major morbidity in Japan, it has not been demonstrated whether a correlation between the calculated RC-NCD risk score and the actual occurrence of mortality and severe morbidity exists.

methodsThe clinical data of 585 patients who underwent pulmonary resection for non-small cell lung cancer were collected, and the risk factors for postoperative morbidity were analyzed to verify the validity of the RC-NCD.

resultsThe coexistence of asthma (p = 0.02), nutrition lymphocyte ratio (p = 0.04), and pulmonary lobe (p < 0.01) were significant risk factors for postoperative morbidity in the present study, and the percent-predicted vital capacity (p < 0.01), pulmonary lobe (p = 0.03), and type of operative procedure (p = 0.01) were significant risk factors for severe postoperative morbidity. Furthermore, in patients received lobectomy, coexistence of asthma (p = 0.01) and pulmonary lobe (p < 0.01) were identified as significant risk factors for postoperative morbidity. Meanwhile, male sex (p = 0.01), high BMI (p < 0.01), low vital capacity (p = 0.04), and pulmonary lobe (p = 0.03) were identified as significant risk factors for severe postoperative morbidity.

conclusionsGiven that the pulmonary lobe was a significant risk factor for postoperative morbidity in patients received pulmonary resection and for severe postoperative morbidity in patients received lobectomy, the RC-NCD for postoperative morbidity needs to be modified according to high-risk lobes.

trial registrationThe Institutional Review Board of Kanazawa Medical University approved the protocol of this retrospective study (approval number: I392), and written informed consent was obtained from all patients.
