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

backgroundFor patients with locally advanced non-small cell lung cancer (NSCLC), the standard treatment is concurrent or sequential chemotherapy with radiotherapy. Most treatment schedules use radiotherapy with conventional fractionation; however, the application of hypofractionated radiotherapy (HYPO-RT) regimens is rising. A meta-analysis was performed to assess the efficacy and safety of chemotherapy combined with HYPO-RT and indirectly compare with the outcomes from previous studies employing concomitant conventional radiotherapy (CONV-RT).

methodsRandomized controlled trials (RCTs) were identified on the electronic database sources through June 2020. Following the PRISMA guidelines, a meta-analysis was performed to assess if there were significant differences in the overall mortality (OM), local failure (LF), and disease progression (DP), comparing HYPO-RT-C

resultsTwo RCTs with a total of 288 patients were included. The RR for the OM, DP and LF at 3 year comparing HYPO-RT-C DISCUSSION: HYPO-RT given with chemotherapy provides satisfactory OM, LF, and DP in locally advanced NSCLC with similar rates to the CONV-RT. These findings support HYPO-RT inclusion in future clinical trials as an experimental arm in addition to the incorporation of new strategies, such as immunotherapy.
