Intensity-modulated radiation therapy for early-stage breast cancer: a systematic review and meta-analysis.

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
backgroundRadiation therapy (RT) is a standard treatment for non-metastatic breast cancer and is associated with acute and late toxicities. Intensity-modulated RT (IMRT) may decrease toxicity and is convenient for patients.
objectivesTo assess the efficacy and safety of IMRT in women with early stage breast cancer. DESIGN AND
settingSystematic review study; Multi-institutional centers.
methodsSeven databases were searched. Randomized controlled trials (RCT) comparing IMRT with any "non-IMRT" strategies were included. Primary outcomes were local control and acute toxicity. Cochrane Handbook was use to plan and conduct the review, and PRISMA 2020 was used to report results.
resultsFive RCT involving 2,556 women (n = 1,283 IMRT; n = 1,274 control arm) were included. Baseline characteristics were similar between trials and arms. Local relapse-free survival rates were not different (hazard-ratio [HR] 0.62; 95%confidence interval [CI] -0.38 to 1.62; P > 0.05); however, IMRT reduced the overall acute toxicity (RR 0.69, 95%CI 0.58 to 0.82; P < 0.00001) and acute moist desquamation (risk-ratio [RR] 0.71, 95%CI 0.60 to 0.82; P < 0.00001). Lymphedema and pneumonitis rates, and survival outcomes were not affected by IMRT. The 2-year telangiectasia rate was decreased with IMRT (RR 0.66, 95%CI 0.47 to 0.93; P = 0.02); however, edema, pain, pigmentation, or fibrosis remained unaffected. IMRT did not improve cosmesis.
conclusionsIMRT improved acute toxicity and lowered telangiectasia rates, without affecting oncological and aesthetic outcomes.
