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

backgroundWe conducted this study among adults with pulmonary tuberculosis (TB) who received treatment, in order to determine the risk factors associated with survival of during treatments.

methodsA retrospective cohort study was conducted from 2005-2015 with newly registered TB patients in the Hospital of Masih Daneshvari Doctor, Tehran, Iran. Overall, 5313 patients met our study's cohort definition, but the analysis was performed on 2299 patients (43.2%) who had a correct address and they could be traced-out by the Medical - registry. Time in days was used in survival model and patients who were still alive (until last follow-up date) considered as censored. To study the effect of risk factors on patients' survival, the generalized gamma regression model was used.

resultsBased on the results of univariate analysis, gender (RR=2 (95% CI: 1.1-3.7), high school education (Relative Risk: RR=0.3 (95% CI: 0.2-0.7), higher education (RR=0.3 (95% CI: 0.1-0.9), smoker (RR=2.5 (95% CI: 1.4-4.2), drug user (RR=2.4 (95% CI: 1.4-4), TB contact (RR=0.5 (95% CI: 0.3-0.8) and HIV positive (RR=4 (95% CI: 1.7-9.2) affected patients' survival. Moreover, the results of multivariate analysis showed that, gender (RR=5.5 (95% CI: 2.2-13.5), age (RR=1.1 (95% CI: 1-1.1), adverse drug effect (RR=2.5 (95% CI: 1.2-5.4), smoker (RR=3.3 (95% CI: 1.2-9.4), TB contact (RR=0.2 (95% CI: 0.1-0.5), diabetic mellitus (RR=3 (95% CI: 1-8.3), HIV positive (RR=26 (95% CI: 4.6-145.9) and comorbidities (RR=4.9 (95% CI: 2-11.6) were identified as factors affecting patients' survival.

conclusionOur data indicated associated risk factors in TB mortality and could suggest way to progressing national tuberculosis program (NTP) for predicating and plan for effective interventional strategies.
