Dose-response relationship of stereotactic body radiotherapy for ultracentral tumor and comparison of efficacy with central tumor: a meta-analysis.
Article in Translational lung cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundUltracentral (UC) tumors, a subset of central lung tumors defined as those that abut the proximal bronchial tree (PBT), have been contraindicated for stereotactic body radiotherapy (SBRT). The present meta-analysis evaluated the efficacy of SBRT for UC and central tumors, and dose-response for local control (LC) of UC tumors.
methodsDatabases including MEDLINE and EMBASE were searched up to March, 2020, to identify studies regarding SBRT for UC and/or central tumors. The primary endpoints were LC and overall survival (OS), while secondary endpoints were grade ≥3 and 5 complications.
resultsFourteen studies including 892 patients were included. In the UC and central tumor groups, the 1-year OS rates were 82.2% and 85.4% (P=0.556), respectively, and the 2-year OS rates were 66.4% and 71.9% (P=0.522), respectively. The 1- and 2-year LC rates in the UC and central tumor groups were 93.9% and 97.8% (P=0.023) and 90.4% and 93.7% (P=0.459), respectively. The pooled grade ≥3 complication rates in the UC and central tumor groups were 9.0% and 4.4% (P=0.06), while the corresponding grade 5 complication rates were 5.7% and 2.1% (P=0.087). The dose-response for LC was shown in the meta-regression (P<0.0001), and 1-year LC rates were significantly different (94.4%
conclusionsThe oncologic outcomes of patients with UC and central tumors were comparable post-SBRT. A dose of at least ≥85 Gy10 is recommended for SBRT of UC tumors. Causes of complications should be further studied as UC tumors are more prone to serious toxicities.
